We are given a small Python code snippet and a set of possible printed outputs. The code assigns a = 5 and b = 10, then prints: The sum of {} and {} is {}.".format(a, b, a+b) which substitutes the values in order: a → 5, b → 10, and a+b → 15, yielding the exact string: The sum of 5 and 10 is 15.

Option A: The sum of 5 and 10 is 15. — This matches the actual printed line produced by the code, including the numeric values and the punctuation.

Option B: The sum of a and b is a + b. — This would be printed if formatting placeholders were not filled with values, or if the strings were taken literally without substitution. The code clearly substitutes the variable values, so this is incorrect.

Option C: The sum of a and b is 15. — This mixes the literal variable names (a and b) with a numeric result, which is not how the string is formed by format(a, b, a+b). Therefore this does not reflect the produced output.

Option D: The sum of 5 and 10 is 5 + 10. — This would require the expression a+b to be printed as the expression itself rather than its evaluated result. The code computes a+b and inserts 15, so this is not what the program outputs.

In summary, option A aligns with the code’s actual output, while options B, C, and D misrepresent how the string formatting fills in the placeholders."

What is a format specifier?

With advanced string formatting, a format specification can include an alignment character that determines how a value should be aligned within the width of the field.
