Q1. The poultry feed includes: (Choose the most appropriate option from below)
A Concentrates and maize only
B Roughage and concentrates only
C Maize and barley only
D Maize, barley, pearl-millet etc. Correct
Explanation
Poultry feed commonly uses cereal grains because they supply energy and are easy to include in balanced rations. Maize, barley and pearl-millet are all recognised grain ingredients in poultry feeding, so the broad group naming these grains and similar items is correct. The phrase limited to concentrates and maize leaves out other cereal ingredients. Roughage is not a main poultry-feed category in the way it is for ruminants, so that pairing is unsuitable. The answer limited to maize and barley is too narrow because pearl-millet and similar grains are also included.
