What control signals may be necessary to operate a 1-line-to-16 line d

1.	What control signals may be necessary to operate a 1-line-to-16 line decoder?(a) Flasher circuit control signal(b) A LOW on all gate enable inputs(c) Input from a hexadecimal counter(d) A HIGH on all gate enable circuitsI had been asked this question at a job interview.I would like to ask this question from Parity Generators/Checkers in chapter Combinational Circuits of Digital Circuits
Answer» Correct ANSWER is (b) A LOW on all gate ENABLE INPUTS To explain: A LOW on all gate enable inputs is necessary to operate a 1-line-to-16 line decoder because enable pins are USUALLY, active-low pins.
