The correct strategy described in this scenario is a short combination. When an investor writes a call and a put option with the same strike price and expiration date, they are engaging in a short combination strategy.

In this case, the investor writes an XYZ October 70 call at a premium of 3 and an XYZ October 70 put at a premium of 1. The total premium received from this strategy is 4 (3 from the call and 1 from the put), which creates an obligation to fulfill the terms of the options if exercised. This strategy is typically employed when the investor believes that the underlying stock will not move significantly in either direction, as they profit from the premiums while risking the potential obligation if the options are exercised.
