1c.  How many clubs does opener have?         >5 clubs<

1d.  What possible distributions does opener have?    >Opener must have 4 diamonds and 5 clubs with the remaining 4 cards in the majors.  With 6+ clubs opener would re-bid clubs before showing the diamond suit.  If opener was 5-5 in diamonds and clubs, opener would open 1 diamond rather than 1 club.  Furthermore, opener must have at least one card in each major.  Otherwise, opener would have either 4 spades or 4 hearts with a void in the other major and would bid the major before bidding 2 diamonds.  Therefore, opener's distribution must be either 1-3-4-5, 3-1-4-5, or 2-2-4-5.<
