Explanation: The Mahanadi River is a significant river in eastern India, primarily flowing through the states of Chhattisgarh and Odisha. It originates in the Maikal Range of the Satpura Hills, near Sihawa in Raipur district of Chhattisgarh. The river flows eastward through Chhattisgarh and then enters Odisha, where it forms a large delta before draining into the Bay of Bengal.
The first statement is correct: the Mahanadi indeed rises near Sihawa in Raipur district of Chhattisgarh. This is a well-established geographical fact and is consistent with the river's origin in the Maikal Range.
The second statement, however, is incorrect. The Mahanadi does not run through Andhra Pradesh. It flows through Chhattisgarh and Odisha, and its course does not extend into Andhra Pradesh. This misconception might arise due to the proximity of Andhra Pradesh to the river's basin, but the river itself does not pass through the state.
The third statement is also incorrect. While a significant portion of the Mahanadi's drainage basin is in Odisha, the exact percentage is not fifty-three percent. The drainage basin of the Mahanadi covers a large area, and the distribution of this basin among the states of Chhattisgarh and Odisha is more complex than a simple percentage can convey. The actual distribution of the drainage basin is such that a larger portion lies in Odisha, but the specific percentage given in the statement is not accurate.
In summary, the correct answer is that only the first statement is accurate. The Mahanadi River originates in Chhattisgarh, and it does not run through Andhra Pradesh, nor does fifty-three percent of its drainage basin lie in Odisha. Understanding the geography and hydrology of the Mahanadi River is crucial for comprehending the ecological and economic significance of this river system in eastern India.
