The correct answer is A. Koderma.
Red micaceous soil is a type of soil that is found in the Koderma district of Jharkhand, India. It is a rich, loamy soil that is ideal for growing crops such as rice, wheat, and maize. The soil is also known for its high iron content, which gives it its characteristic red color.
Dumka, Giridih, and Netarhat are all located in the Jharkhand state of India. However, they do not have red micaceous soil. Dumka is located in the Santhal Parganas division of Jharkhand. The soil in Dumka is mostly alluvial soil, which is a type of soil that is formed from the deposition of sediments by rivers. Giridih is located in the Palamu division of Jharkhand. The soil in Giridih is mostly lateritic soil, which is a type of soil that is formed from the weathering of rocks. Netarhat is located in the Surguja division of Chhattisgarh. The soil in Netarhat is mostly red lateritic soil, which is a type of soil that is formed from the weathering of igneous rocks.
Red micaceous soil is a valuable resource that is essential for the agricultural economy of Jharkhand. The soil is also important for the environment, as it helps to regulate the water cycle and prevent soil erosion.
