Option a

Explanation:

A protective put position can be defined by buying or owning stock and buying put options on a share-for-share basis. It is a "risk-management strategy" that uses the options contracts which investors employ to guard themselves against the loss of owning a stock or asset. In this strategy, traders believe that the price of the asset may decline in the future.

For example: Suppose 50 shares are purchased (or owned) and one put is purchased. So, when the stock price declines, the purchased put protects the strike price.
