Identify the segment in the sentence which contains a grammatical error.
Sentence: Starting with cleaning the kitchen, Reema created a task list of all the odd jobs that were to do around the house.

Correct option is B

Option (b) contains an error.
The phrase “that were to do” is grammatically incorrect.
It should be: “that were to be done around the house.”
“to be done” is the correct passive form needed here, as the jobs are to be done by someone, not doing themselves.
Grammatical rule used:
Use of Passive Infinitive — "to + be + past participle" for actions performed by an unspecified agent.
Example:
Correct: All the tasks are to be completed by Friday.
Incorrect: All the tasks are to complete by Friday.
Information Booster:
In passive structures, verbs requiring an agent (doer) should use the passive infinitive form.
