D. -$1,116

Explanation:

Total amount of purchase = number of shares * price per share

= 300 * $8.62

= $2,586

Total dividends received = number of shares * dividend per share

= 300* $0.10

= $30

Total proceeds from sale of shares = number of shares sold  * price per share

= 300* $4.80

= $1,440

Total dollar return = (Total proceeds from sale of shares + Total dividends received - amount of purchase)

= $1,440 + $30 - $2,586

= -1,116
