Fun fact: the word "diet" can be used as a noun, a verb, and an adjective! What do you think the correct answer is? Thanks, LearnEnglish – British Council, for this great quiz.
The
correct answer is "C" because he/she diet specifically, so the preposition
used is "on" because the preposition "on" used to specify
(something/someone) then followed the noun which is "stick". I'm not
using the transitive verb " follow" because it something/someone to do.
"On" is used to express that you are undertaking/taking/committing (to) something as in "you are committing to your diet"; "stick" because it can co-occur with the preposition "to". The "to follow to it" is ungrammatical because the verb "follow" nor the infinitive "to follow" cannot co-occur or be used next to the preposition "to".
