The limitations on asking a question of a committee chair are narrow and well known. Page 552 of Practice says:

A question to a committee chair asking when a report would be tabled has been permitted.

So the first part of that question I think would be in order. It continues:

A question asking if a committee had been requested to inquire into a certain matter has not been permitted.

Extrapolating from that limitation, it's quite clear that the second part of that question is not in order.
