The correct answer is option 2, Egypt. Long staple type of cotton refers to a specific variety of cotton that has long, fine fibers. This type of cotton is preferred for producing high-quality textiles, especially luxury fabrics. Egypt is known for producing long staple cotton, which is called Egyptian cotton. It is valued for its softness, strength, and ability to produce fine, smooth fabrics. While other countries like India, Greece, and China also cultivate cotton, they are more commonly associated with growing other types of cotton with different fiber characteristics. Therefore, Egypt is the main country where long staple cotton is grown.
