The correct answer is B. 495

Here is the expression written in MathJax:

The number of ways to select 8 subjects from 12 subjects is given by the binomial coefficient “12 choose 8”, which can be calculated as follows:

\(_{12}C_{8} = \frac{12!}{8!(12-8)!} = 495\)

So, there are 495 ways to select 8 subjects from 12 subjects for an examination. The correct answer is B. 495.
