U mean MCQ C ....r u sure it was not D tht is 3 only coz my friend put up a valid point tht it sasked for a changes tht wud provide both these(catalyst does not incr conc) and tht there was a similar question abt it in past pprs...I chose C(wht u said) coz o the reasons u also thought wud make C the answer
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'

I agree,i interpreted it your way,but now i see awesome has a valid point too....it was ambiguous since they didnt state both...
