Professional Machine Learning Engineer exam

You are going to train a DNN regression model with Keras APIs using this code: How many trainable weights does your model have? (The arithmetic below is correct.)A . 501*256+257*128+2 = 161154B . 500*256+256*128+128*2 = 161024C . 501*256+257*128+128*2=161408D . 500*256*0 25+256*128*0 25+128*2 = 40448View AnswerAnswer: C
