The correct answer is based on polyester's properties as a fabric. Polyester is known for being resistant to water and is less likely to absorb liquids compared to natural fibers, but it can absorb and hold onto oily materials due to its oleophilic (oil-attracting) nature. This means it is more susceptible to oil stains than fabrics like cotton or linen, which tend to repel oils. Therefore, the statement about polyester readily absorbing and holding oily materials accurately reflects one of its characteristics.

In contrast, polyester is generally recognized for good resistance to sunlight, making it an excellent choice for outdoor applications. It is also treated with flame retardants in many cases or woven in a way that reduces flammability. Additionally, polyester fibers are indeed resilient and elastic, retaining their shape and resisting wrinkling and stretching. These properties highlight the differences between synthetic and natural materials, emphasizing the unique advantages polyester offers in various applications.
