The p-value for a two-tailed test is found by doubling the area in the tail beyond the observed test statistic. Since the z-score is 1.75, we look up the area in one tail in a standard normal distribution table, which gives us approximately 0.0401. Doubling this for both tails gives us 0.0802, which corresponds to choice B.
