Cd= cc * cv.
And the value of Cc& Cv is always less than unity.
Eg : cc = 0.9 and cv = 0.9
Cd = 0.9 * 0.9
Cd = 0.81
And the value of Cc& Cv is always less than unity.
Eg : cc = 0.9 and cv = 0.9
Cd = 0.9 * 0.9
Cd = 0.81

A is right option.
Because of Cd = Cc * Cv.
Cc is less and Cv is high and ultimately, Cd is less than the Cv.

Cd = Cc * Cv.
Where Cc is always less than unity and Cv.
So Cd will be always less than Cv.
Where Cc is always less than unity and Cv.
So Cd will be always less than Cv.
