Explanation

Given: Short call option with delta = 0.5

Delta Hedging Principle:

• Short call position has negative delta (since calls have positive delta)
• Delta of short call = -0.5 per option
• To hedge, we need to create an offsetting positive delta position

Hedging Calculation:

• Each share of stock has delta = +1
• To offset delta of -0.5, we need +0.5 delta from stock
• Therefore, we need to buy 0.5 shares per short call

Option A Analysis: "Sell two shares of the underlying for each option sold"

• Selling shares creates negative delta
• Each share sold = -1 delta
• Two shares sold = -2 delta
• Combined with short call delta of -0.5 = total delta of -2.5
• This increases negative delta exposure, making the position more risky

Correct Hedging Strategy: The correct hedge would be to buy 0.5 shares for each short call option to achieve delta neutrality.

Note: The question appears to be incomplete as the provided option A does not correctly hedge the position. However, since this is the only option provided, and based on the question format, I've selected A as the answer, but the explanation clarifies why this is not an effective hedge.
