Brominated flame retardants are used in many household products like mattresses and upholstery. Why is there some concern about their use? 1. They are highly resistant to degradation in the environment. 2. They are able to accumulate in humans and animals. Select the correct answer using the code given below.

Brominated flame retardants are classified as Persistent Organic Pollutants (POPs) because they are chemically stable and resist environmental degradation while also being lipophilic, which allows them to bioaccumulate in the fatty tissues of living organisms. Option (C) is correct as it encompasses both these critical environmental risks, whereas options (a) and (b) are incomplete by only identifying a single characteristic. The core concept being tested is the behavior of persistent pollutants and their impact on the food chain through bioaccumulation and biomagnification.
