The correct answer is - to produce recombinant that leads to genetic variation.
Explanation:
Random shuffling or random alignment of the chromosome during gamete formation allows the formation of new allele combinations. In the crossing over the parts of the homologous chromosomes are switched between homologous and recombinants are formed that shows are genetic variation.
So, now they have different allele combinations and chromosome combinations as well. Random shuffling does not provide genetic variations as crossing over
