Explanation:

Step1: Find common denominator

The common - denominator of 4 and 3 is 12.

Step2: Rewrite fractions with common denominator

$\frac{1}{4}=\frac{1\times3}{4\times3}=\frac{3}{12}$, $\frac{1}{3}=\frac{1\times4}{3\times4}=\frac{4}{12}$.

Step3: Add the fractions

$\frac{3}{12}+\frac{4}{12}=\frac{3 + 4}{12}=\frac{7}{12}$.

Answer:

C. $\frac{7}{12}$
