A parent wants to put aside savings for his 20-year-old disabled daughter to use at...

Target-date funds (also called life-cycle funds) automatically adjust their asset allocation (glide path) over time. They start with a growth-oriented strategy (more equities) and gradually shift towards conservative allocations as the target date approaches.

This matches the father’s goal: minimal management required while allowing for growth in earlier years and reduced risk later.

Balanced equity, high-yield income, and global equity funds do not automatically shift allocations over time.

Thus, the most appropriate choice is Target date fund.
