Consider the following code snippet. What is the potential problem with the if statement?

double average;

average $=($g$1+$ g$2+$ g$3+$ g$4)/4\mathrm{.}0$;

if $($average $==90\mathrm{.}0)$

$\{$

System.out.println$("$You earned an A in the class!"$)$;

$\}$

Group of answer choices

The assignment operator should not be used within an if$-$statement conditional.

Using $==$ to test the double variable average for equality is error$-$prone.

The conditional will not evaluate to a Boolean value.

Literals should never be used in if statement conditionals.
