The correct answer is:  0.9 cal 

Explanation:

The formula for the specific heat (s) is:

s = (q)/(m * ΔT) --- (1)

Where
s = Specific heat = 0.09 cal/g°C
m = mass (make sure it is in GRAMS) = 10g
ΔT = Change in temperature = 21° - 20° = 1°
q = Heat Energy = ?

Plug in the values in the Equation (1):
(1) => q = (10*1*0.09) = 0.9 cal
