The answer is B. According to the script, Zoe states, "A good example of that is plastic bottles, which are heavier than most other plastics and therefore relatively easy to handle and sort." This means that (B) is correct because plastic bottles weigh more than other types of plastic, as mentioned directly by Zoe. Options (A) and (C) are incorrect; she does not say they lack an end market or are time-consuming to sort.

The answer is B. Zoe states in the script, "While it is technically possible to recycle most plastics, the complexity and cost of doing so has prevented this happening in the past." This clearly supports that most types of plastic can be recycled, making (B) the best choice. She does not say some or all types only—she specifically says most.

The answer is A. Zoe says, "Yes, and it also uses water, so then you have to balance the water usage against the resources saved by recycling the plastic." This shows that having to wash the plastic before recycling it reduces the environmental benefit because water is used, so environmental gain may be offset by water consumption.

The answer is C. Zoe says, "By the way, the UK has a much higher use of HDPE bottles than most countries as we use them to contain milk rather than glass bottles." This means the UK uses more HDPE bottles than other countries, which supports option (C).
