Answer:
The risk of a portfolio declines as the number of stocks in the portfolio increases.
Explanation:
In simple words, diversification refers to the benefit of lesser risk that a manager gets by adding negatively or less correlates securities in the portfolio.
However, it is a fact that risk can only be minimized and cannot be eliminated completely. The risk that is specific to the business is called systematic risk and due to its unpredictability it cannot be diversified away.
Thus, from the above we can conclude that the correct option is A.
