$A = 1/2ab sinC$

This is simply a case of learning the correct formula for the area of a triangle.

You need to have the combination of three facts as
'Two sides and the included angle,"

Angle $C$ lies between sides $a and b$ and is therefore the included angle.

The correct formula is

$A = 1/2ab sinC$ which is the last option offered,

The 5. answer

$A=1/2*h_b*b$
$h_b/a=sin(C)|*a$
$h_b=a*sin(C)$

$A=1/2a*b*sin(C)$
