  1, 3, 5

Step-by-step explanation:

The interest earned is given by the formula ...

  I = Prt

For the reference amount, that is ...

  I = ($150)(0.04)(2) = $12

For the choices, the earned interest amounts are ...

  1) ($300)(.02)(2) = $12

  2) ($150)(.06)(1.5) = $13.50

  3) ($400)(.03)(1) = $12

  4) ($100)(.01)(8) = $8

  5) ($50)(0.48)(0.5) = $12

Accounts 1, 3, 5 would earn the same interest.
