Identify the segment in the sentence which contains the grammatical error.
His investors have extended their support to him and the unforeseen situation for many years now.
Correct Answer : c ) His investors have extendedExplanation :
The error is in part c.
To express a period of time/ a long span of time, ‘for’ is used.
Example- for 8 weeks, for 4 days, etc.
Also, when the period of time is mentioned and the action expressed is one that started in the past and is still in continuation, we use present perfect continuous tense.
So, it will be ‘have been extended’ instead of ‘have extended’.
Hence, (c) is the correct answer.
