Martinez has recently hired Kenneth Singh to help him evaluate portfolios. Martinez asks Singh about the possible effects on the portfolio's information ratio if cash were added to the diversified asset portfolio or if the aggressiveness of the portfolio's active weights were increased. Singh responds with two statements:Statement 1: Adding cash to the portfolio would change the portfolio's information ratio.Statement 2: Increasing the aggressiveness of active weights would not change the portfolio's information ratio.

Option A:The bond subportfolio.
Option B:The equities subportfolio.
