Answer» Correct Answer - Option 4 : Electrically operated machines are preferable to use Given statements: i). All machines consume energy. ii). Electricity provides energy. iii). Electrically operated machines are cheap to maintain. iv) . Electrically operated machines do not cause pollution. Let us now examine the given inferences: 1) All machines are run by electric energy. → False (as it is possible but not definite) 2) There is no form of energy other than electricity. → False (as it is possible but not definite) 3) Most machines are operated on electric energy. → False (as it is possible but not definite) 4) Electrically operated machines are preferable to use. → True Hence, 'Electrically operated machines are preferable to use' is the correct answer.

Answer» Correct Answer - Option 4 : Electrically operated machines are preferable to use

Given statements:

i). All machines consume energy.

ii). Electricity provides energy.

iii). Electrically operated machines are cheap to maintain.

iv) . Electrically operated machines do not cause pollution.

Let us now examine the given inferences:

1) All machines are run by electric energy. → False (as it is possible but not definite)

2) There is no form of energy other than electricity. → False (as it is possible but not definite)

3) Most machines are operated on electric energy. → False (as it is possible but not definite)

4) Electrically operated machines are preferable to use. → True

Hence, 'Electrically operated machines are preferable to use' is the correct answer.
