Correctly Matched Pairs of Plastics and Characteristics:

1. Acrylics - Very good transparency to light
Acrylics are known for their excellent transparency to light, making them a popular choice for applications where visibility is important, such as in windows, displays, and lighting fixtures.

2. Polypropylene - Excellent fatigue strength
Polypropylene exhibits excellent fatigue strength, meaning it can withstand repeated loading and unloading without failing. This characteristic makes it suitable for use in products that undergo constant stress or movement.

Explanation:
The correctly matched pairs in this question are 1 and 4, which correspond to Acrylics and Polypropylene, respectively. Acrylics are indeed known for their very good transparency to light, while Polypropylene is recognized for its excellent fatigue strength. Therefore, option c) 1 and 4 is the correct answer.
