Solution
The correct option is B B As per stoichiometry, 7 mol of A will react with 13 mol of B and 15 mol of C
Finding the limiting reagent, For A=given molesstoichiometric coefficient=157=2.14 For B=given molesstoichiometric coefficient=2613=2.00 For C=given molesstoichiometric coefficient=30.515=2.03
Since the ratio is the least for B, it will be the limiting reagent.
