An option series consists of:

a) all options of the same type, traded for the same underlying asset, with the same exercise price and same expiration date.
b) all options of the same type, traded for the same underlying asset with the same exercise price.
• c) all options of the same type, traded for the same underlying asset with the same expiration date.
  No. For example, a call and a put on Alcoa stock both maturing in October but having different exercise prices do not belong to the same series.
