111

Step-by-step explanation:

It is given that $a_{1}=-12$ and $a_{27}=66$ , thus

$a_{1}=-12$ ,

$a_{2}=a_{1}+d=-12+d$ ,

$a_{3}=a_{2}+d=-12+2d$ ,

.........

$a_{27}=-12+26d$

⇒ 66=-12+26d

⇒ 78=26d

⇒ d=3

therefore, the value of $a_{42}$ will be:

$a_{42}=a_{1}+41d$

= -12+41(3)

= 111

Thus, $a_{42}=111$

Therefore, C is the correct option.
