The correct answer is - খ) leave

• Bare Infinitive Usage:
  (a) After modal verbs: can, do, may, must, shall, will, would, have, should
  - I may help you.
  - He must do it.
  (b) Auxiliary use of need and dare:
  - I dared not wake him.
  - They need not do anything.
  - Affirmative: I need to buy a pen.
  (c) After verbs like please, see, know, hear, bid, feel, let, make, watch:
