Suppose an electronics manufacturer knows from previous data that 1% ofone type of an electronic component are defective. The quality controlinspector randomly selects components until a defective one is found. Is thisa binomial experiment? Why or why not?O A. This is a binomial experiment, because the situation satisfies allfour conditions for a binomial experiment.O B. This is not a binomial experiment, because the number of trials isnot fixed.C. This is not a binomial experment, because each trial cannot beclassified as a success or failure.D. This is not a binomial experiment, because the trials are not
