OA D . Why is A wrong?
In A, a wave cannot reach UP...to 200 feet HIGH. The object of a preposition (to) cannot be a modifier (200 feet high). Also, UP and HIGH are redundant. Eliminate A.

In B, up to 150 miles per hour IN SPEED is not parallel with HEIGHTS of up to 200 feet. Eliminate B.

In C and E, are (plural) does not agree with a tsunami (singular). Eliminate C and E.

The correct answer is D.

A conjunction such as and must connect PARALLEL FORMS.
B: that can reach UP...and HEIGHTS
Here, up (preposition) and heights (noun) are not parallel forms.
Eliminate B.
