b.

Yes, using conditional jump instructions.

c.

No, most instructions are too primitive for that.

d.

No, variables cannot be tested in assembly language.

Answer: (c).No, most instructions are too primitive for that. Explanation:It is not generally possible to test a variable’s value and act on that value in a single instruction in assembly language, as most instructions are too primitive for that. Instead, the value of a variable must be tested, flags set based on the test, and a conditional branch instruction invoked that tests the necessary flags and branches if they indicate that the operand handled in the most recent instruction was zero.
