Answer - Option C is false
Explaination-
Option A is accurate. The broker does have the right to sell securities to take care of the liabilities if you do not pay attention to a margin call.
Option B is also correct, though the difference in short term is not very high. Note that Option C is incorrect as AM or arithmatic mean is always greater than or equal to geometric mean.
Theoretically, you have unlimited loss potential on short sale. Thus, Option D is correct.
Option E is correct according to Portfolio Performance research (Brinson, Hood, Beebower, 1986)
