The odd one out is A. Turban.
A turban is a headdress worn by men in some parts of the world. It is typically made of a long piece of cloth that is wrapped around the head. Turbans are often worn for religious or cultural reasons.
A skirt is a piece of clothing that is worn around the waist and covers the lower body. Skirts can be made of a variety of materials, including fabric, leather, and fur. They come in a variety of styles, including miniskirts, maxi skirts, and A-line skirts.
A sari is a traditional Indian garment that is worn by women. It is a long piece of cloth that is wrapped around the body in a specific way. Saris are often brightly colored and decorated with intricate patterns.
A frock is a type of dress that is typically worn by young girls. It is a short dress that is often made of light, flowing fabric. Frocks are often decorated with ruffles, lace, or other embellishments.
A turban is a headdress, while the other three are garments.
