Answer 1

Answer:

The correct answer is letter "A": survivorship bias.

Explanation:

Survivorship bias or survivor bias, in finance, refers to the tendency of concentrating in past winner actions of a given asset -usually stocks, and dismissing the losers. When analyzing mutual funds under this approach, outdated or merged funds are not included, taking into consideration only the valid funds as the current performance for the whole chunk.
