Statement (1) Child A is holding the seesaw at a 30 degree angle with the end touching the ground.

With just the angle, we cannot calculate the height of the seat B. Insufficient

Statement (2) Point x is 2 feet above the ground and is at the midpoint of the seesaw.

This statement may suggest to apply the idea of similar triangles and find the height : 2/L = H/2L => H = 4 (L is the hyp of smaller rt triangle)

But, in my opinion for this to work, the end A of the see saw should touch the ground. It doesn't look like that from the figure, so Insufficient.

Combining St1 & St2, we can easily calculate the height using pythagorean triplets. Answer should be C.

I feel 2nd statement us sufficient. I suggests that x is the midpoint of the seesaw hence the height of x from ground has to be half of the height of the end point of the seesaw from the ground
