Solution
We would prefer the parallel wiring. This is done for the following reasons:
(i) In parallel wiring, each lamp can have its independent switch and the disconnection (putting off) of one of them will not effect the other lamps.
(ii) All lamps have the same potential difference (equal to that of the mains) across the terminals and are thus able to work as per their specified rating.
