The time period (T) of oscillation of a simple pendulum for small oscillations is given by the formula T = 2π * sqrt(L / g), where L is the length of the pendulum and g is the acceleration due to gravity. From this formula, it is clear that the time period T is directly proportional to the square root of the length L (T ∝ sqrt(L)). Therefore, if the length of the pendulum increases, the time period also increases.

The time period of a simple pendulum is proportional to the square root of its length.

The formula T = 2π * sqrt(L / g) also shows that the time period depends on the acceleration due to gravity (g) but is independent of the mass of the pendulum bob and the amplitude of oscillation (provided the amplitude is small). Option A correctly describes the relationship between T and L.
