If you use a table, then here is one table you can use http://users.stat.ufl.edu/~athienit/Tables/Ztable.pdf it's similar to what you find in many (if not all) stats textbooks in the appendix section go to page 2 and locate the row that has 1.3 at the very left. Mark the entire row. Do the same for the column that has 0.03 at the top I've done so in the attached image below note how the row and column intersect at 0.9082 Therefore the answer is choice D) 0.9082

This website http://onlinestatbook.com/2/calculators/normal_dist.html offers the same basic function as the table; however it allows for quicker calculation, not just for areas to the left of the z score. Plus it gives a handy graph as well.
