Now consider European options on GOOG with Expirations other than 6 months. Suppose there also exists a forward contract on GOOG with 12-month forward price = F₁₂.

1. First consider 12-month European options on GOOG. What can we say about the relative value of a European put on GOOG with K = F₁₂, and a European call on GOOG with K = F₁₂?

2. What can you say about the relative values of a European calls and puts on GOOG if they are struck at some K > F₁₂?

3. What can you say about the relative prices of T-month European puts and calls if both options have K = F_T?
