Which of the following sentences uses the correct form of the verb 'to lie'?
Correct: C
The sentence 'I lay in bed all day' uses the incorrect form of the verb 'to lie'. The correct sentence would be 'I lay down in bed all day' or 'I have lain in bed all day'. 'Lay' is the past tense of 'to lie' and requires the preposition 'down' to indicate the action of reclining. 'Lied' is the past tense of 'to lie' as in telling an untruth.
