answer is c
you can take current i as x then it will be
2+x+4+5-2=1 which gives x =-8 since x is negative we have current going towards right (decreasing)

answer: 8a towards right...
firsttake all the inputs as 2a+3a+4a+2a= 11a
now sum the outputs..
thats 1a +2a =3a
now 11a-3a =8a
and since 8a current should be let out..... it comes as output so its towards right....
