Concept:Emphatic stress is used to contrast the capitalised word with another word of the same category in the question.
Explanation:The given sentence is: “She will send a BAG to him today.”
The word in capital letters is “BAG”.
Therefore, the stress falls on the object that she will send.
This means the sentence is correcting something else that was suggested as the object to be sent.
For example, if someone asks, “Will she send a shirt to him today?”, the natural reply is, “She will send a BAG to him today.”
Option A changes “today” into “tomorrow”, affecting time, not the object.
Option C changes “she” into “he”, affecting the subject.
Option D changes “him” into “her”, affecting the indirect object pronoun.
Only option B directly contrasts “shirt” with “BAG” in the object position.
Thus, the question to which the given sentence is the appropriate answer must be option B.
Answer:B. Will she send a shirt to him today?
