• C. less; more; less
• D. more, more, more

Answer 1

The correct option is A less; less; more

Heat produced in the current carrying wire depends on:

1) Material of the conductor
2) Length of the conductor: When this is less, heat generated is less.
3) Thickness of the conductor: When this is more, heat generated is less.
