correct answer is: Nylon
Explanation: Nylon is a synthetic polymer manufactured using petroleum products. It is a strong and durable fabric commonly used in clothing and textiles. Other synthetic fibers like polyester (Terylene) are also made from petroleum, but Nylon is the correct answer among the given options. Natural fibers like cotton and silk are not made from petroleum.

• OPTION a: Rayan Silk
  - Likely a synthetic silk, but not necessarily made from petroleum.
• OPTION b: Terelyne
  - Probably a misspelling of Terylene (polyester), which is made from petroleum, but not the intended answer here.
• OPTION c: Nylon
  - Correct, as it is a synthetic fabric made from petroleum products.
• OPTION d: Cotton
  - A natural fiber from plants, not made from petroleum.
