Choose the option that best completes the gap(S).The Bank Manager assured us that there was nothing to worry about _____ ?
Answer Details
The correct option is "with regard to the loan". This is because "with regard to" means "concerning or regarding something" and is often used to introduce a subject that is being discussed or to indicate the subject matter of a statement. In this sentence, the speaker is saying that the Bank Manager assured them that there was nothing to worry about concerning the loan. The other options either use incorrect prepositions or use the incorrect plural form of "regard".
