A
$$133$$

B
$$51$$

C
$$26$$

D
$$13$$

Solution

The pattern is as follows.
$$\Rightarrow 10+16=26$$
$$\Rightarrow 13+24=37$$(Adding $$16+8=24$$)
$$\Rightarrow 26+32=58$$(Adding $$24+8=32$$)
$$\Rightarrow 37+40=77$$(Adding $$32+8=40$$)
$$\Rightarrow 58+48=106$$(Adding $$40+8=48$$)
$$\Rightarrow 77+56=133$$(Adding $$48+8=56$$).
