In the given sentence, identify the segment which contains a grammatical error.
We've decided to spend our time play online games as we will not go out on a vacation this year.

Correct option is B

Option (b) contains an error.
Explanation of Error:
The segment “play online games” is incorrect in this structure. The verb “to spend” should be followed by a gerund (verb + ing), not the base form of the verb.
· Correct form: to spend our time playing online games
So, the correct structure should be:
We've decided to spend our time playing online games as we will not go out on a vacation this year.
Grammatical Rule Used:
When a verb like "spend" is followed by another verb, the second verb usually takes the -ing form (gerund), especially when talking about how time or money is used.
· Example: He spends his evenings reading.
· Incorrect: He spends his evenings read.
Information Booster:
Common verbs followed by gerunds: spend, enjoy, avoid, consider, finish, suggest.
Hence, the error lies in option (b).
