Answer:

B

Explanation:

To find
y=f(g(x)), substitute the value of
g(x) into the the function f(x) instead of x.

Consider option B:

Given


f(x)=(7)/(√(x))\\ \\g(x)=8x+10

So,


f(g(x))\\ \\=f(8x+10)\ [\text{Expression } 8x+10\text{ has a role of }x]\\ \\=(7)/(√(8x+10))

This is exactly what you need as answer.
