from basic formula,
Q=CV (Q=charge,C-capacitance,V=electric potential)
C=Q/V
Q-->(current*time)AT
V-->(energy/charge(here,energy->ML^2T^-2) )ML^2T^-2/AT = ML^2T^-3A^-1
C-->Q/v->A^2M^-1L^-2T^4
in your question,Farad is the unit of capacitance..
answer is option a..
A2s4kg-1m-2
since it is the si units,all the units in the options must also be so..
