what do you mean split? are they 3 different ranges you got from your RIR or
is that private subnet

You can create reverse zone for /16 (b.a.in-addr.arpa) or /24
(c.b.a.in-addr.arpa). It's easier to mainsain smaller files (256 reverse
zones for /24) but it's probably easier to register reverse for /16 if
that's public address space.
