Explicação passo-a-passo:

$\tt \: basta \: calcularmos : \\ \tt \: \\ \frac{1}{3} + \frac{1}{4} = \frac{7}{12}$

$\tt \: pegamos \: = > 3 \times 4 = 12$

$\tt \: assim \: temos : \\ \\ \tt \: \frac{4}{12} + \frac{3}{12} \\ \\ \tt \: agora \: aplicamos \: a \: \\ \tt \: propriedade\: de \: frações \: : \\ \tt \: \frac{a}{b} + \frac{b}{c} = \frac{a + b}{c} \\ \\ \tt \: assim \: temos : \\ \\ \tt \: \frac{4 + 3}{12}$

$\tt \: somamos \: = > 4 + 3 = 7 \\ \tt \: e \: temos \: a \: resposta : \\ \\ \tt \: = \frac{7}{12} \\ \\ \tt \: sendo \: a \: alternativa \: d \\ \tt \: a \: resposta \: correta \: .$
