The unit digit of 5 is always 5, so in this we need to know the unit digit of 9^5m
From statement 1:- given that m is odd and then the unit digit of 9^5m is 9, sufficient.
From statement 2:- given that n is even then unit digit of 5^3n is 5 but we don't know the unit digit of 9^5m , Insufficient
Answer is [A].

what is the units digit of \(5^{3n} + 9^{5m}\) ?
for any power to 5 except when 0 , the unit digit is always 5
and for 9 at odd powers is 9 and even is 1
we need to basically find value of m
#1
m is an odd integer
sufficient
unit digit is 5
#2
n is an even integer
insufficient as m is not known
option A
