Assertion (A): One of the important requirements of a carburettor is to supply leanmixture at starting.Reason (R): A rather lean mixture is required at No-load and low-load operation of a SI engine.  
  • a)
    Both A and R are individually true and R is the correct explanation of A
  • b)
    Both A and R are individually true but R is not the correct explanation of A
  • c)
    A is true but R is false
  • d)
    A is false but R is true
Correct answer is option 'D'. Can you explain this answer?
