A simple pendulum is being used to determine the value of gravitational acceleration $g$ at a certain place. The length of the pendulum is 25.0 cm and a stopwatch with 1 s resolution measures the time taken for 40 oscillations to be 50 s. The accuracy in g is:
(1) $5.40\%$
(2) $3.40\%$
(3) $4.40\%$
(4) $2.40\%$
