Which of the following instruments would not be classified as a financial liability?
(a) A preference share that will be redeemed by the issuer for a fixed amount of cash on a future date (i.e., the entity has an outstanding share that it will repurchase at a future date).
(b) A contract for the delivery of as many of the entity’s ordinary shares as are equal in value to $100,000 on a future date (i.e., the entity will issue a variable number of own shares in return for cash at a future date).
(c) A written call option that gives the holder the right to purchase a fixed number of the entity’s ordinary shares in return for a fixed price (i.e., the entity would issue a fixed number of own shares in return for cash, if the option is exercised by the holder, at a future date).
