An investor is classified as a "risk taker" and is looking at two possible investments: investment A has an expected return of $18\%$ with a standard deviation of $12\%$ and investment B also has an expected return of $18\%$ with a standard deviation of $6\%.$ The risk taker investor would pick

Investment A

Investment B

Either one, it doesn't matter since they both have the same expected return

Both investment A and investment $B$
