If the isosceles triangle ABC is also equilateral, then regardless of which point you choose as A and side BC, the altitude is congruent to the median (i.e. probability is 1). If ABC is not equilateral, then this is true only for one vertex (i.e. probability is 1/3). Therefore, the answer is D.

The possibilities can also be given as:

1. AB=BC<=>AC
2. BC=AC<=>AB
3. AC=AB<=>BC
4. AB=BC=AC

Thus required probability for Scenario A is in case: 3. AC=AB<=>BC and 4. AB=BC=AC.
Hence, A=1/2

Thus A. Quantity A is greater.
