A customer holds 1,000 shares of Company XYZ and wants to sell covered calls against...

Each option contract represents 100 shares. A covered call involves selling a call option while holding an equivalent number of shares to deliver if the option is exercised.

The customer owns 1,000 shares.

Since 1 contract = 100 shares, the maximum number of contracts the customer can sell is:1,000 shares ÷ 100 shares/contract = 10 contracts.

B is correct because selling 10 contracts corresponds to 1,000 shares, fully covering the position.
