Select the correct option to fill in the blank no.3
Show answer & explanation
Correct answer: C
Explanation
The correct answer is option 4 i.e. to.
Context: The sentence is explaining that the destination and itinerary are kept a secret from the customer — that means the customer does not know them.
Meaning of the words:
to – shows the receiver of the action
from – used to show where something starts or is taken away from
with – means together with
till – means until a certain time
Correct word: to is the right word here because the secret is given or revealed to the customer — so the correct phrase is: “a secret to the customer”.
Reason: In English, we often say something is a secret to someone (means they don't know it). Even though “from” may seem possible, in this structure, “to” fits correctly with “a secret”.
Final Sentence: …kept the destination and itinerary a secret to the customer..
Hence, the chosen option is correct.
