The following sentence has been split into four segments. Identify the segment that
contains a grammatical error.
She was happy to find out that the child could lay there all day without being disturbed by anyone.

Correct option is A

Option (a) contains an error. The correct verb should be "lie" instead of "lay." In this context, "lie" is used to describe the action of the child remaining in a reclining position, whereas "lay" requires an object as it means to place something down.
· Grammatical rule used: "Lie" (to recline) is an intransitive verb that does not require a direct object, and its present tense is "lie," past tense is "lay," and past participle is "lain." "Lay" (to put down) is a transitive verb requiring a direct object, with the present tense "lay," past tense "laid," and past participle "laid."
· Example: The book lies on the table. (correct use of "lie") vs. She lays the book on the table. (correct use of "lay")
