A bookkeeping mistake
a) may be be corrected when discovered
b) includes adding players to the scorebook during game
c) must be corrected before the halftime intermission
d) may be corrected if recognized during the first dead ball following the mistake
It isn't B or C. I think they left of some important information in a) like "before the R approves the score". Sure you "may" correct it in D .. but you don't have to
