Parts of the following sentence have been given as options. Select the option that contains an error.
"Sanchit has been read since early morning for his class test."

Explanation of the Correct Answer:
· The phrase "Sanchit has been read" is grammatically incorrect.
· "Read" is a verb, not something that happens to a person.
· The correct structure should be "Sanchit has been reading."
· This is present perfect continuous tense, which correctly conveys an action that started in the past and is still ongoing.
Other options:
· (a) "for his" → Correct; "for his class test" is properly structured.
· (b) "class test." → Correct; "class test" is a valid noun phrase.
· (d) "since early morning" → Correct; "since" is used appropriately with present perfect continuous tense.
Thus, the correct sentence should be:
"Sanchit has been reading since early morning for his class test."
The incorrect part is (c) "Sanchit has been read."
