Photons absorbed in matter are converted to heat. A source emitting \( n \) photon/sec of frequency \( v \) is used to convert \( 1 \mathrm{~kg} \) of
\( \mathrm{P} \) ice at \( 0^{\circ} \mathrm{C} \) to water at \( 0^{\circ} \mathrm{C} \). Then, the time \( T \) taken for the

W conversion
(a) decreases with increasing \( n \), with \( v \) fixed.
(b) decreases with \( n \) fixed, \( v \) increasing
(c) remains constant with \( \mathrm{n} \) and \( v \) changing such that \( n v= \) constant.
(d) increases when the product \( n v \) increases.
