Mark is a representative for EBIX Securities. He has a client named Jennifer who would like to trade $10\mathrm{.}000$ shares of ELY, a stock with little trading volume. The last large$-$block trade for the stock was several days ago, and it is currently trading at $$5\mathrm{.}50/$share$.$ Because Jennifer is so eager to sell her shares, Mark suggests that she offer it for a price significantly below $$5\mathrm{.}50$ in order to gauge interest in such a large trade. She agrees, and they offer the stock for $$\frac{5\mathrm{.}30}{?}$ share. Within minutes an investor offers to buy the shares at $$5\mathrm{.}30.$ At that time, Mark and Jennifer agree to hold out for a higher offer. Which of the following is true of Mark's course of action?

A It is allowed since his client did not promise to sell ot $$5\mathrm{.}30$

B It is prohibited becouse he and his client are not allowed to bock awoy

It is allowed as long as Mark and Jennifer do not loter sell the shares for $$5\mathrm{.}30$ or less

It is prohibited becouse representotives must always trade a security ot its morket rote
