This type of method cannot access any non-static member variables in its own class.
- a. instance
- b. void
- c. static
- d. non-static

Static methods cannot be accessed by any non-static member variable within a class
Hence, the correct answer is option “C”.
Explanation of Solution
Static method:
Static is an access modifier which cannot be accessed and is applicable on block, variable, methods, nested classes. Static keyword is added while declaring the block or variable or methods. A static member can be accessed before any objects of its class are created, and without even using the reference to any object.
Explanation for incorrect options:
a. Instance:
Instance variables are declared without the static keyword and are present outside any method declaration.
Hence, the option “A” is wrong.
b. Void:
Void describes the return type of the method, where void means the method has no return value.
Hence, the option “B” is wrong.
d. Non-static:
Non-static variables can be accessed by any member variable.
Hence, the option “D” is wrong.

This ALU will implement a bitwise left rotation. Forthis lab assignment you are not allowed to use Digital's Arithmetic components.IF YOU ARE FOUND USING THEM, YOU WILL RECEIVE A ZERO FOR LAB2!The ALU you will be implementing consists of two 4-bit inputs (named inA and inB) and one 4-bit output (named out). Your ALU must rotate the bits in inA by the amount given by inB (i.e. 0-15).Part-1: User InterfaceYou are provided an interface file lab2_part1.dig; start Part-1 from this file.NOTE: You are not permitted to edit the content inside the dotted lines rectangle. Part-1: ExampleIn the figure above, the input values that we have selected to test are inA = {inA_3, inA_2, inA_1, inA_0} = {0, 1, 0,0} and inB = {inB_3, inB_2, inB_1, inB_0} = {0, 0, 1, 0}. Therefore, we must rotate the bus 0100 bitwise left by00102, or 2 in base 10, to get {0, 0, 0, 1}. Please note that a rotation left is…arrow_forwardSolve this "Do not use AI tools.
