Answer:
The correct option is A.
Explanation:
As we know that genetic variation that result from crossing over depend on the number of genes and their alleles. When there are more genes in genome the chances of polymorphic loci will increase, which will result into more genetic variation during crossing over.
Forexample:
Drosophila melanogaster is a common fruit fly having diploid number of 8 chromosome composed of 122,653,977 base pairs, and about ~17,000 genes. Honey bees have diploid number of 32 chromosomes composed of approximately 2360000 base pairs, and 10,000 genes.
Conclusion:
As fruit fly genome contain more genes and polymorphic loci, so genetic variation is more likely to be greater in fruit fly.
The first organisms to inhabit Earth were prokaryotes that
lived 3.5 billion years ago. prokaryotes are well organised, achieving all of an organism’s life functions
within a single cell. These were the precursors to eukaryotic cells

Explanation:
The Big Five trait dimension or the five factor model is based on descriptors of personality. The big five traits are:
Openness
Beuroticism
Agreeableness
Extraversion
Conscientiousness
From these, the trait expressed is Extraversion. This trait is characterized by outgoing and energetic behavior. Energy creation is gained through external means.
