The consumer's risk can be calculated using the table G.1. With a sample size of 75 and acceptance number of 3, the corresponding code letter is K. Using this code letter and the given AQL and LTPD, the consumer's risk is estimated to be 0.48. This means that there is a 48% chance of accepting a lot with a true proportion defective greater than or equal to the LTPD. Therefore, the best choice is B.
