Critical Reasoning (CR) | Re: A rare type of bacterial has killed off many tuna fish in North

E is best answer

We know that tuna meat price is increased but tuna based cat food price

If it's other ingredients price is decreased then we are not sure whether price would increase or not
But if price of other ingredients remains same then its price can go up
E goes in both ways so it sbest option

B doesn't correlate with situation ,in argument we know nothing about consumer behaviour so it is wrong

All other options are not addressing concern of price for tuna based cat food
