Question Analysis
This question evaluates the student's understanding of the relationship between the number of protons, neutrons, and the mass number of an isotope.

Key Concept Explanation
The mass number (A) of an isotope is the sum of the number of protons and neutrons in its nucleus.

Step-by-step Solution
1. Identify the number of protons and neutrons in the isotope.
Number of protons = 14
Number of neutrons = 16
2. Calculate the mass number (A) using the formula: A = number of protons + number of neutrons.
