Consider the three parts:

A. Consider a call option to buy 100 shares for $30 per share. How should terms be adjusted for a 3-for-2 stock split?

B. Consider a put option to sell 100 shares for $10 per share. How should terms be adjusted for a 15% stock dividend?

C. An investor writes two naked call option contracts on a stock. The option price is $8, the strike price is $35, and the stock price is $33. What is the margin requirement for the options?
