These are all true except <span>"D. Natural selection usually causes a species to change suddenly," which is false. Natural selection and the subsequent changes to a species takes many thousands of years to have observable results. </span>
The type of mutation that occurred here is an inversion of three nucleotide bases (Option A).
<h3>What is an inversion?</h3>
An inversion is a type of mutation where linear order of nucleotide in the mutated sequence is inverted.
In this case, we have an inversion that involves the following bases (bold highlighted) AATCGC TAC GCACGTCAG and AATCGC CAT GCACGTCAG.
In conclusion, this mutation is an inversion of the genomic sequence (Option A).
