• C. Inbreeding
• D. Superiority

Answer 1

Answer: (A), (B)

The correct options are
A Heterosis
B Hybrid vigour

An offspring produced by crossing two pure lines is called an F1 hybrid. Because we have pure lines being crossed, the F1 hybrids we get have the superior qualities of both parents, and the tendency of hybrids to acquire the superior characteristics of both the parents is called hybrid vigour or heterosis.
