Direction: The following sentence has been split into four segments. Identify the segment that contains a grammatical error. I am / walking in the / Cross Road Garden / since morning.

Explanation

Here, the erroneous part is "I am." Key Points The segment "I am" contains a grammatical error. The use of "since morning" is correct to indicate the duration of time. "Since morning" indicates the duration, so the present perfect continuous tense ("have been walking") is appropriate for describing an action that started in the past and continues into the present. The correct answer is Option 4. Correct sentence: I have been walking in the Cross Road Garden since morning.
