Identifying Call or Put Option: Financial Claim with Initial Value and Payoff

This problem involves a financial claim with the following information:

• Initial Asset Value: S_0 = 10 at time t=0
• Asset Value at Time t=1: S_1 = {3, 14}
• Financial Claim Payoff at Time t=1:
  • F = 0 if S_1 = 3
  • F = 5 if S_1 = 14

Determining Call or Put:

The claim pays off only when the asset price reaches a higher value (S_1 = 14). This indicates a put option as the holder profits when the asset price falls below a certain level (the strike price).

Determining Strike Price:

Since the claim pays off 5 when the asset price is 14, we can infer that the strike price (k) is 25. This is because the payoff of 5 represents the difference between the strike price (25) and the asset price at time t=1 (14).

Answer:

Put, k=25
