Q1: An OR array is programmed by blowing fuses to eliminate selected variables from the output functions.

ANS:A - True

A programmable logic device (PLD) is an integrated circuit (IC) that is user programmable to form customised logic circuits within the same IC. There are many forms of this device, however, a typical device usually contains a large array of cells, where each cell consists of a group of connected AND/OR gates. A type of "fuse" makes the connection between these gates, and programming involves blowing the necessary fuses to produce a logic circuit.
