[Solved] Which of the following arithmetic expressions is identical to the expression a += b * c [closed]

Question

A. x += y is just shorthand for x = x + y, the compiler always expands it out as such

B. C# isn’t like math where you can rearrange an equation as you wish. As such, you can’t have an expression such as a+b on the lefthand side of an assignment, which is what the = does. How would you store the value of c in a+b? it just isn’t logical so this is the clear wrong answer. In programming, = does not have the same meaning as an equals sign in a mathematical equation.
