Using the law of sines, we can write the formula as:

$\frac{a}{sin(A)}= \frac{b}{sin(B)} \\ \\ 
b= \frac{a*sin(B)}{sin(A)}$

We are given the values of a, A and B. Using these in the above formula, we get:

$b= \frac{36*sin(78)}{sin(34)} \\ \\ 
b=62.97$

Rounding to nearest integer, the length of side b will be 63.

So, option C gives the correct answer
