This is known as "5 take 3", where ordering is not important.

In the given scenario above, the one who will be named as
the external stimulus is the action of having to use the sense of sight when
you have seen the fruit of bowl. The internal stimulus will be the action of having

<span>Depending on the equation there can be three possible cases:
1- There can be 1 specific solution for the variable:
2x+4= 3
where x= -1/2
2- there can be an infinite amount of solutions:
2x+x-2=3x-3+1
where x=x
3- there can be no answer:
3+2x-x=5-3x+4x
where the solution doesn't exist</span>
I would say the answer is C
