The period of a simple pendulum can be calculated using the formula: 
T = 2π(L/g)^(1/2)
where T is the period, L is the length of the pendulum, and g is the acceleration due to gravity. 
Rearranging this formula to solve for L, we get: 
L = (gT^2)/(4π^2)
Plugging in the given values, we get: 
L = (9.8 m/s^2)(2.0 s)^2/(4π^2) = 0.99 m
Therefore, the correct answer is C.
