Answer 2

C. None of the above

Explanation:

we know that

The number of students who signed up for different after school activities are

Cooking------------> 9 students

Chess---------------> 4 students

Photography-----> 8 students

Robotics-----------> 11 students

Total of students -----> (9+4+8+11)=32

Verify each statement

case A) The ratio of photography students to all is 4:1

The statement is false

Because the ratio of photography students to all is 8:32

Simplify

1:4

case B) For every 1 chess student there are a total of 16 students

The statement is false

Because the ratio of chess student to all is 4:32

Simplify

1:8

so

For every 1 chess student there are a total of 8 students

therefore

C. None of the above
