To determine which naming conventions are not proper, we need to evaluate each item against common programming naming rules. 
Option a: i. CourseCode. This is a single word written in PascalCase or camelCase style depending on capitalization; many languages allow CourseCode as a valid identifier. It is commonly used in languages that favor no separators between words, so this can be considered proper in several conventions. 
Option b: ii. Crs_Code. This uses an underscore between words but shows mixed capitalization (Crs_Code). In many naming schemes, snake_case would use all lowercase with underscores (e.g., crs_code). The mixed capitalization here (Crs vs Code) makes it inconsistent with typical snake_case or camelCase conventions, which can be seen as ill-formed or at least non-idiomatic in standard style guides. Additionally, some languages are case-sensitive for identifiers, so the irregular capitalization could cause readability or stylistic concerns. Therefore, this is not a proper or clean naming convention in common guidelines. 
Option c: iii. Course_Code. This uses an underscore to separate words with all lowercase after each word capitalized only at starts of words; however, the typical snake_case convention would be all lowercase (course_code). The Camel/Pascal casing mixed with underscores is less conventional and can be considered non-idiomatic in many coding standards that prefer either camelCase (courseCode) or snake_case (course_code). Still, it is not inherently invalid as an identifier in many languages, but it is not the standard form in common guidelines. 
Option d: iv. Course Code. This contains a space between words, which is not allowed in identifiers in nearly all programming languages. A space would separate tokens and is invalid as a single identifier in standard naming conventions. This is clearly not proper. 
Now comparing the options, the question asks which is NOT a proper naming convention. While i and iii can be argued as acceptable in certain contexts, and ii is already non-idiomatic due to inconsistent capitalization, iv is universally invalid due to the space. The provided answer indicates the NOT proper ones are ii and iv, which aligns with the fact that both ii (due to inconsistent capitalization that breaks standard snake_case style) and iv (due to the space) are not proper naming conventions in typical coding standards. 
In summary: 
i. CourseCode — generally acceptable in camelCase/PascalCase contexts. 
ii. Crs_Code — not a clean, standard form due to inconsistent capitalization with underscores. 
iii. Course_Code — closer to snake_case but not all-lowercase; still often considered non-idiomatic though not universally invalid. iv. Course Code — invalid in almost all languages due to the space. 
Hence, the most defensible choice for NOT proper naming conventions, given common style guides, is ii and iv.
