Read the following statements :
(A) When small temperature difference between a liquid and its surrounding is doubled the rate of loss of heat of the liquid becomes twice.
(B) Two bodies \( P \) and \( Q \) having equal surface areas are maintained at temperature \( 10^{\circ} \mathrm{C} \) and \( 20^{\circ} \mathrm{C} \). The thermal radiation emitted in a given time by \( P \) and \( Q \) are in the ratio \( 1: 1.15 \)
(C) A carnot Engine working between \( 100 \mathrm{~K} \) and \( 400 \mathrm{~K} \) has an efficiency of \( 75 \% \)
(D) When small temperature difference between a liquid and its surrounding is quadrupled, the rate of loss of heat of the liquid becomes twice.
Choose the correct answer from the options given below :
(a) A, B, C only
(b) A, B only
(c) A, C only
(d) B, C, D only
