Final answer:
Mrs. Verona's account is entitled to receive dividends on 1,000 shares of ABC Corporation stock.
Step-by-step explanation:
To determine how many shares of ABC Corporation stock Mrs. Verona's account is entitled to receive dividends on, we need to consider the dates of her purchases and sales. The ex-date is the date on which a stock begins trading without the dividend. Any shares bought on or after this date will not be entitled to receive dividends. Mrs. Verona purchased 1,000 shares on 05/02, which is before the ex-date of 05/11, so she is entitled to receive dividends on those shares. Therefore, the answer is b. 1,000 shares.
