It was D
Catalysts do not increase the yield. They only increase the rate of reaction by lowering the activation energy

the wording of question cud be interpreted in either ways...Like for choosing C
we had to identify thoses changeS tht wud increase both rate and yield...
So choosing D wud mean tht 3 is the only option where as we cud use catalyst and pressure rise to overall increase both factors.
So in this context D is partial answer and wud be incorrect..
But if I were to go with D..then there is wht u said..Oh the ambiguity

Was D; Only 3
If it was not, then the answer is not D
The answer basically was ' only 3'
