Anew combination of hereditary material is produced in offspring through
asexual reproduction
sexual reproduction

The correct answer would be sexual reproduction.

Sexual reproduction leads to the development of genetic variation in the offspring in two ways:

Crossing over: Exchange of genetic material between non-sister chromatids of homologous chromosomes takes place during the formation of gametes.  

Fertilization: The two gametes fertilize to form a zygote. Thus, the genetic material of zygote is contributed by both the parents.

These two factors form a new combination of genes in an offspring which is different from either parent.
