More is the steric hindrance around the N of amine, lesser is the ΔG for inversion because it has the least tendency to invert)
Most steric hindrance is in C. Therefore it has lowest ΔG for inversion.

@jai-d-gr8 in Q it is lowest so ∆G# could be -ve na??
means more spontaneous???
@Ashish-Singh They are considering the absolute value of change in free energy ...if they were so particular about the sign of free energy change the question would have been, which among the following amine inversions inversions is the most spontaneous ..
