When product-related safety problems occur, consumers have a responsibility to
a. discard the product
b. report the problem to the seller and the manufacturer
c. sue the seller
d. demand a full refund

I think that they key word here is "responsibility" - it's not about what the consumers want , but about what is responsible, that is: what will also be beneficial for others and for the society in general.

The responsible option here would be to b. report the problem to the seller and the manufacturer- this way other people can be warned and not endangered. 

Ithink the answer you are looking for is (b).

Okay perfect i'll be sure to do that lol
