Solution

The correct option is D
4

Given,
$3 \times 1^{2} + 6 a + 2 = 29$

$\Rightarrow 3 \times 1 + 6 a + 2 = 29$

$\Rightarrow 3 + 6 a + 2 = 29$

$\Rightarrow 5 + 6 a = 29$

Transposing 5 from LHS to RHS, we get,

$6 a = 29 - 5$

$6 a = 24$

Transposing 6 from LHS to the RHS, we get,

$a = \frac{24}{6}$

$a = 4$
