Assertion (A): A load-and-go assembler avoids the overhead of writing the object program out and reading it back in. Reason (R): This can be done with either a one-pass or a two-pass assembler.

1. ABoth (A) and (R) are true and (R) is the correct explanation of (A)
2. BBoth (A) and (R) are true but (R) is NOT the correct explanation of (A)
3. C(A) is true but (R) is false
4. D(A) is false but (R) is true

Show answer & explanation

Correct answer: C. (A) is true but (R) is false

Explanation

A load-and-go assembler places code directly in memory, avoiding writing the object program out and reading it back (A true). It can be one-pass or two-pass (R true), but that does not explain A.

Note on the official key: the official key says option A. Official/PW key is A. Beck notes a load-and-go assembler can be one-pass or two-pass, so R is true, but it does not explain why A holds; option B fits.
