Answer:
Option B is the correct answer.
Explanation:
Period of simple pendulum is given by the expression [tex]T=2\pi \sqrt{\frac{l}{g}}[/tex], where l is the length of pendulum and g is the acceleration due to gravity value.
So if we have a simple pendulum with length l we can find its period. Using the above formula we can calculate  acceleration due to gravity value of that place.
So using simple pendulum we can measure acceleration due to gravity value.
Option B is the correct answer.
