100 POINTS AND BRAINLIEST!! PRE CALC! Which of the following expressions is equivalent to (cos x + tan x)/sin x

a. cot x + sec x
b. cos x + cot x
c. tan x + sec x
d. sin x + tan x

Please explain your answer :)

Step-by-step explanation:

Expand the fraction \frac{\cos\left(x\right)+\tan\left(x\right)}{\sin\left(x\right)}

sin(x)

cos(x)+tan(x)

 into 22 simpler fractions with common denominator \sin\left(x\right)sin(x)

\frac{\cos\left(x\right)}{\sin\left(x\right)}+\frac{\tan\left(x\right)}{\sin\left(x\right)}

sin(x)

cos(x)

+

sin(x)

tan(x)
