what type of ANOVA should I use?

#1
population =30
Breaking it down

Number of male participants =20
Number of Female Participants = 10

Number of Working Participants(W) = 8
Number of Non-Working participants(nW) = 22

I surveyed the students and here are given the raw datas (multiple choice for question number one) where I didnt yet consider the variables such sex and occupation:

A = 12
B= 4
C=14

Now I tabulated the variables
M____F____W___nW
12----3-------2----5------A
2-----1-------3----2------B
6-----6-------3----15-----C


I want to know if what type of anova should I use here
given the raw data where I didn't take the account of variables such as sex (m and f),working and non working variables.
I wish to know if the raw data still holds its significance that students prefer the answer C after having the results from the test.
