I think the answer is (b) i.e.., 12 in BODMAS method.

B-Bracket,O-of,D-division,M-multiplication,A-addition,S-subtraction.

3+3*3-3+3= 3+9+3+3-3
=12+3-3
=15-3    =12.

The right answer is 12

If we use the rule of DMAS [division,multiplication.addition.subtraction{full form: BODMAS(bracket of division,multiplication,addition,subtraction)}], then in

3+3x3-3+3, 

we will first multiply 3x3
                            = 9
then the equation would become : 3+9-3+3
then, we would add 3+9
                            = 12
12-3+3

=> 12+3
     = 15
15- 3
= 12

therefore, the answer is 12
