You may lose your license
a. when you turn 70 years old.
b. if you accumulate too many points on your driving record.
c. if you stop driving for more than five years.

I know its not A. It could be B. but not all states have a point system. I doubt it would be C. because how would they know if you haven't driven in 5 years?? best bet is C. Good Luck!!

Ifound the exercise on the internet. attached is the list mentioned above.in order for a compound to be considered optically active it can't have any axis or plan of symmetry. the molecule  shouldn't also  be superimposable on its mirror image.with such considerations, the compounds that are optically active are: -third compound on the first image is optically active; -second and third compound from the second image are optically actives.
