The correct option is A The teacher rewarded the student for scoring a hundred percent in his test.
In the English language, the normal order of words in a sentence is:
subject + verb + object. The subject is the performer of the action
(verb) and the object is the receiver of that action.
In the given
sentence, the object "the student" is placed before the verb
"rewarded", whereas it should be placed after. Hence the sentence requires
change and option A is incorrect.
Option B is correct as the
sentence follows the normal word order subject (The teacher) + verb
(rewarded) + object (the student).
Option C is incorrect because the words are not in the required order: object + verb + subject.
Option D is incorrect because the verb "rewarded" is placed before the subject "teacher", which isn't the normal word order.
