The correct answer is: D. final stock price.
An original investment plus an expected capital gain is used to calculate the final stock price. The formula is:
Final stock price = Original investment + Expected capital gain
The original investment is the amount of money that you originally invested in the stock. The expected capital gain is the amount of money that you expect to make from the stock. The final stock price is the price of the stock at the end of the investment period.
For example, if you originally invested $100 in a stock and you expect to make a capital gain of $20, then the final stock price would be $120.
Option A, final stock, is incorrect because it is not a formula. Option B, expected stock, is incorrect because it is not the final stock price. Option C, expected final stock price, is incorrect because it is not a formula.
