The answer is:

A.

h(x)=9x-13

To solve the problem, we need to perform the shown operation.

We have the functions:

$f(x)=2x-1\\g(x)=7x-12$

So, performing the following operation, we have:

f(x)+g(x)=h(x)

h(x)=f(x)+g(x)=(2x-1)+(7x-12)=7x+2x-1-12=9x-13

h(x)=9x-13

Hence, we have that the correct option is:

A.
h(x)=9x-13

Have a nice day!
