Increasing the number of stocks in a portfolio from 10 to 25 would likely:
Systematic risk is risk in the economic system. This risk impacts all stocks. This risk cannot be removed.
Unsystematic risk is risk specific to particular stock.

Therefore, Increasing the number of stocks will decrease the variation in returns the investor faces in any one year.
Therefore option C is correct.
