$\bold{BY}$

Answer 2

He should be here Right Now.

• The missing word is to be placed in the blanks. The missing word can be either "Right" or "by".So the sentence can be also, He should be here By Now.
• The actual meaning of "Right" is either right side or correct thing but here the word right now means absolutely now or as soon as possible.
