B) column B
C) column C
D) column D

The proportion associated with the highest 35% of the normal distribution is 1 - 0.35 = 0.65. We then look in column C of the normal distribution table, which corresponds to values between 0 and 0.5. We need to find the area to the left of this value, so we can either subtract 0.5 from the value in the table and use the corresponding z-score or use the value in the table for 0.5 and subtract it from 1 to get the area to the left of it (0.5 in a standard normal distribution corresponds to a z-score of 0).
