D)   Sell a European call option; sell a European put option; invest the present value of the exercise price in a riskless pure-discount bond.

The correct answer was C)

According to put-call parity we can write a stock position as: S₀ = C₀ – P₀ + X/(1+R_f)^T

We can then read off the right-hand side of the equation to create a synthetic position in the stock. We would need to buy the European call, sell the European put, and invest the present value of the exercise price in a riskless pure-discount bond.

The correct answer was C)

According to put-call parity we can write a European call as: C₀ = P₀ + S₀ – X/(1+R_f)^T

We can then read off the right-hand side of the equation to create a synthetic position in the call. We would need to buy the European put, buy the stock, and short or issue a riskless pure-discount bond equal in value to the present value of the exercise price.

The correct answer was A)

According to put-call parity we can write a riskless pure-discount bond position as:
X/(1+R_f)^T = P₀ + S₀ – C₀.

We can then read off the right-hand side of the equation to create a synthetic position in the riskless pure-discount bond. We would need to buy the European put, buy the same underlying stock, and sell the European call.
