Photons absorbed in matter are converted to heat. A source emitting \(n\) photon/sec of frequency \(\nu\) is used to convert \(1~\text{kg}\) of ice at \(0^{\circ}\text{C}\) to water at \(0^{\circ}\text{C}.\) Then, the time \(T\) taken for the conversion:
(a) decreases with increasing \(n,\) with \(\nu\) fixed
(b) decreases with \(n\) fixed, \(\nu\) increasing
(c) remains constant with \(n\) and \(\nu\) changing such that \(n\nu=\) constant
(d) increases when the product \(n\nu\) increases

 
Choose the correct option:

1. (b), (d) 2. (a), (c), (d)
3. (a), (d) 4. (a), (b), (c)
