Explanation / Answer

SAT score of 1490 has z value

= (1490 - 1518) / 325

= -28 / 325

= -0.086 = -0.09

An ACT score of 17.0 has z value

= (17.0 - 21.1) / 4.8

= -0.8542 = -0.85

Since -0.09 > -0.85,

The SAT score of 1490 is relatively better than the ACT score of 17.0.

The incorrect option is B.
