A portfolio manager is considering investing $100,000 and has the following information about three portfolios with normally distributed returns:

Expected Annual Return | Standard Deviation of Returns Portfolio 1: 23% | 15% Portfolio 2: 12% | 6% Portfolio 3: 15% | 8%

If the manager aims to withdraw $5,000 in one year without depleting the initial capital, which portfolio is the safety-first optimal choice?
