Answer

\text{C}

4 steps

Substitute the given values $a=3$ , $b=6$ , and $c=4$ into the numerator of the expression.
Numerator: $5a - 7 = 5(3) - 7$
$5(3) - 7 = 15 - 7 = 8$
Substitute the given values $a=3$ , $b=6$ , and $c=4$ into the denominator of the expression.
Denominator: $2a + b + c = 2(3) + 6 + 4$
$2(3) + 6 + 4 = 6 + 6 + 4 = 16$
Divide the numerator by the denominator.
$\frac{8}{16} = \frac{1}{2}$
Compare the result with the given options.
The calculated value is $\frac{1}{2}$ , which corresponds to option C.

The final answer is $\text{C}$ .
