Answer: Choice D

=====================================

Explanation:

Abbreviations:
sec = secant
cot = cotangent
cosec = cosecant (csc is also a widely used abbreviation)

Let's go through the answer choices one by one

Choice A is false because secant involves the hypotenuse

Choice B is false because opposite/adjacent is the ratio for tangent

Choice C is false because cosecant (csc) involves the hypotenuse

Choice D is true. This is the proper ratio for secant. It is the reciprocal of the ratio for cosine. Recall that cosine's ratio is adjacent/hypotenuse.
