Answer:E. 20 m/s^2Explanation:The period of a pendulum is given by the following equation:

Where T = time period (in seconds)

L = length of pendulum

and g = acceleration due to gravity

Substituting the values from the question we get:Solving for g, we get:g = 19.74 m/s^2Closest option to this is option (E).
