The sentence given in option (d) is erroneous. In that sentence, the syntax for 'prefer- to' is incorrectly used as the preposition 'than' is used in place of 'to'.
The correct sentence is 'She prefers walking in the evening to walking in the morning'.
Other sentences are grammatically correct and meaningful.
Hence, the correct answer is option (d).

I. The teacher scolded the child for being late.
II. We're going to a party.
