**Answer:**

<h3>In case of b, c, d ,e volatility is less than that of original stock</h3>

**Explanation:**

The formula to compute the volatility of a portfolio

Here,

The standard deviation of the first stock is σ₁

The standard deviation of the second stock is σ₂

The weight of the first stock W₁

The weight of the second stock W₂

The correlation between the stock c

a) If the correlation between the stock is +1

Hence, the volatility of the portfolio is 0.33 0r 33%

b) If the correlation between the stock is 0.50

Hence, the volatility of the portfolio is 0.29 0r 29%

c) If the correlation between the stock is 0.00

Hence, the volatility of the portfolio is 0.23 0r 23%

d) If the correlation between the stock is -0.50

Hence, the volatility of the portfolio is 0.17 or 17%

e) If the correlation between the stock is -1

Hence, the volatility of the portfolio is 0

<h3>In case of b, c, d ,e volatility is less than that of original stock</h3>
