Choose the most appropriate option to fill in the blank in the given…

The correct answer is Option (3) → never

An adverb is a word that tells how, when, where or how much something happens. It can also describe an adjective or another adverb, for example she sings sweetly, very hot.

Complete sentence: My daughter probably thinks I am making up the stories about my childhood although she never says so and continues to listen patiently. "Although" sets up a contrast: the speaker thinks the daughter doubts the stories, yet the daughter does not say so and goes on listening patiently. Only never gives this contrast, and it explains why the speaker can only say "probably".

Option	What it tells	Example
(1) frequently	often. If she often said so, there would be no contrast with "although", and the speaker would know rather than "probably" think.	He frequently travels to Delhi.
(2) always	at all times. It has the same problem as "frequently" and clashes with "listen patiently".	She always reaches school on time.
(3) never (answer)	Never means at no time.	He never complains, though his job is hard.
(4) categorically	firmly and without any doubt. "Categorically says so" would remove the doubt in "probably thinks".	The minister categorically denied the charge.
