Answer

option a is correct.

explanation: since angular momentm L= mcr then from this m = L/cr ----> equation 1

and since from definition distance r = velocity x time so in this given case it would be   r= CT put this value in expression of m ,(equation 1 )

therefore :  m = L/ C(CT) =  L/ C2T =  h/C2T =  express in exponents  which gives you the option A
