When can we exercice an option?
American options (like those on ADBE) can be exercised by the holder anytime before expiration. They will be exercised automatically at expiration if they are in the money. However, if there is still time before expiration (as in this case), and they are not extremely in the money, there is probably extrinsic value to the option, and you should sell it, not exercise it. European options are only automatically exercised at expiration, and only if they are in the money. These are usually cash settled on products like SPX or VIX. They can not be exercised before expiration, but can be sold anytime.
