Consider a function named avg, which accepts four
numbers and returns their average. Which of the following is a
correct call to the function avg?

The question asks for a correct call to a function named avg that accepts four numbers and returns their average.
First, we need to ensure the function is invoked with exactly four numerical arguments, since that is what the function signature requires.
Option availability: The provided input shows answer entries that appear to be the same line: 'average = avg(2, 3.14, 4, 5)'. While the answer_options field is empty, the given answer text demonstrates a valid form for calling avg and assigning its result to a variable named average.
Syntactic correctness check: avg(2, 3.14, 4, 5) uses four numeric literals, separated by commas, inside parentheses, which is the standard syntax for calling a function with four arguments in many programming languages.
Semantic correctness check: Since avg is defined to compute the average of four numbers, passing 2, 3.14, 4, and 5 provides four numerical inputs, so the function should return (2 + 3.14 + 4 + 5) / 4, assuming a typical average implementation.
Assignment aspect: Prefixing with 'average = ' assigns the result of the function call to the variable average, which is a common pattern for storing the computed average for later use.
Language-specific considerations: While the exact syntax for function calls can vary slightly between languages (e.g., some require different assignment operators or variable declarations), the core form avg(… four numbers …) is the correct shape, and the inclusion of an assignment is typically acceptable if the language supports it.
Addressing the lack of explicit answer options: Since the answer_options field is empty, we cannot evaluate multiple-choice choices here. However, the line shown in the provided answer content is a valid and correctly formed call to avg with four numeric arguments and optional assignment to a variable, which aligns with the problem statement.
In summary, the expression avg(2, 3.14, 4, 5) (optionally prefixed with 'average = ' to store the result) is a correct usage for the described function signature.
