The expected capital gain is calculated by taking the expected final stock price and subtracting the original investment. In this case, the expected final stock price is Rs 45 and the original investment is Rs 25, so the expected capital gain is Rs 45 – Rs 25 = Rs 20.00.

Option A is incorrect because it is the expected final stock price, not the expected capital gain.

Option B is incorrect because it is the negative of the expected capital gain.

Option C is incorrect because it is the difference between the expected final stock price and the original investment, but in the opposite direction.
