Answer:
0.047424
Explanation:
Given that
Expected return of security M = 17%
Standard deviation of Security M = 32%
Expected return of security S = 13%
Standard deviation of security S = 19%
And, the correlation coefficient = 0.78
So, by considering the above information the co variance is
= Correlation coefficient × Standard deviation of Security M × Standard deviation of security S
= 0.78 × 0.32 × 0.19
= 0.047424

Hope that helps.
