A  0.065 kg block on a horizontal frictionless surface is attached to a spring whose force constant is 290 N/m. The block is pulled from its equilibrium position at x = 0 m to a displacement x = +0.080 m and is released from rest. The block then executes simple harmonic motion along the x-axis (horizontal). The displacement of the block at time t = 0.90 s is closest to: 
A)
 
-0.07 m 
B)
 
0.07 m 
C)
 
-0.05 m 
D)
 
0.05 m
