Show answer & explanation

Correct answer: C. (A)-(IV), (B)-(II), (C)-(I), (D)-(III)

Explanation

Firmware is software permanently etched into read-only memory, matching (IV). A batch file, in classic batch-processing terms, is a sequential job file kept in plain ASCII/text format for the batch monitor to read, matching (II). Packing (blocking) is exactly the technique of fitting a number of logical records into one physical disk block to cut down I/O overhead, matching (I). The Banker's algorithm is the standard deadlock-avoidance resource-allocation technique, matching (III). This gives A-IV, B-II, C-I, D-III, option (iii).
