Joe Johnson received 100 shares of Delta Inc. preferred as a tax-free stock dividend because of his ownership of its common stock. At the time of its distribution, the preferred had a value of $20 per share. Had a cash dividend of equal value been paid instead, 75% of it would have been taxable as a dividend.

A.$750
B.$1,000
C.$1,500
