Correct Answer:

Produces a large number of small-sized offspring - Birds

Explanation:

The correct answer is Option (3) -Produces a large number of small-sized offspring - Birds

Under a particular set of selection pressures, organisms evolve towards the most efficient reproductive strategy. Some organisms breed only once in their lifetime (Pacific salmon fish, bamboo) while others breed many times during their lifetime (most birds and mammals). Some produce a large number of small-sized offspring (Oysters, pelagic fishes) while others produce a small number of large-sized offspring (birds, mammals).
