we will proceed to calculate each case to determine the solution of the problem

case A
f(3)=9

For
x=3


x > 0

so


f(x)=x^(2)

substitute the value of x


f(3)=3^(2)=9


9=9

The statement case A is True

case B
f(4)=0

For
x=4


x > 0

so


f(x)=x^(2)

substitute the value of x


f(4)=4^(2)=16


16\\eq0

The statement case B is False

case C
f(2)=4

For
x=2


x > 0

so


f(x)=x^(2)

substitute the value of x


f(2)=2^(2)=4


4=4

The statement case C is True

case D
f(1)=-3

For
x=1


x > 0

so


f(x)=x^(2)

substitute the value of x


f(1)=1^(2)=1


1\\eq-3

The statement case D is False
