what is the answer. Please show workings.

Some food retailers propose subjecting food to a low level of radiation in order to improve safety, but sale of such "irradiated" food is opposed by many people. Suppose a grocer wants to find out what his customers think. He has cashiers distribute surveys at checkout and ask customers to fill them out and drop them in a box near the front door. He gets responses from 119 customers, of whom 73 oppose the radiation treatments. What can the grocer conclude about the opinions of all his customers? Choose the correct answer below, filling in any input boxes as necessary. O A. The grocer can conclude, with 95% confidence, that the proportion of all his customers that oppose "irradiated" food falls in the interval (]) (Round to four decimal places as needed, Use ascending order.) O B. Probably nothing, because the grocer's poll does not meet the 10% Condition. C. Probably nothing, because the grocer's poll does not meet the Success/Failure Condition. O D. Probably nothing, because those who bothered to fill out the survey may be a biased sample
