To determine what prints, I’ll walk through the code step by step and then evaluate each option.
First, text is assigned the string " Hello, World! ". The line s1 = text.strip().lower() removes surrounding spaces and converts to lowercase, giving "hello, world!".
Next, s2 = s1.replace("hello", "hi").replace("world", "there") processes two replacements in sequence: replacing 'hello' with 'hi' yields "hi, world!", and then replacing 'world' with 'there' yields "hi, there!".
Then, s3 = s2[0].upper() + s2[1:] + "!" takes the first character of s2, makes it uppercase, appends the remainder of s2, and finally adds an exclamation mark. Since s2 is "hi, there!", s2[0].upper() becomes 'H' and s2[1:] is "i, there!"; concatenating results in "Hi, there!" followed by another "!" yields "Hi, there!!".
Now let’s examine the answer options one by one:
- Option 1: "Hi, there!" — This is almost correct but misses the extra exclamation at the end. The code explicitly appends a final "!", so this option is missing the second exclamation.
- Option 2: "hi, there!!" — This would be correct if the first letter remained lowercase after capitalization, but the code uppercases the first character, so the string should start with an uppercase 'H'. Because the first character is capitalized, this option misrepresents the case of the initial letter.
- Option 3: "Hi, there!!" — This matches the result computed by the code precisely: the first letter is capitalized, the middle content is unchanged, and there is a trailing second exclamation.
- Option 4: "Hi, world!" — This would occur if the replacements did not happen or if the final string had not been altered to replace 'world' with 'there'. However, s2 has already transformed to "hi, there!", so this option does not reflect the actual outcome.
In summary, option 3 is consistent with the transformation steps (lowercase to lowercase, replacements replacing 'hello' with 'hi' and 'world' with 'there', then capitalizing the first letter and adding a final exclamation). The other options fail due to incorrect casing, incomplete punctuation, or incorrect replacement results.
