Explanation: The Ganges River, also known as the Ganga, is one of the most significant rivers in India and plays a crucial role in the country's geography, culture, and religion. Originating from the Gangotri Glacier in the Himalayas, the Ganges flows through the northern plains of India, passing through several states including Uttarakhand, Uttar Pradesh, Bihar, and West Bengal. It also flows through parts of Bangladesh, which was historically known as East Bengal.
The Ganges River is approximately 2,525 kilometers (1,569 miles) long and is considered sacred by Hindus. It is a major source of water for millions of people, supporting agriculture, industry, and daily life. The river's course through India and Bengal is marked by numerous tributaries and distributaries, which further expand its influence.
The Ganges eventually meets the Bay of Bengal, a marginal sea of the Indian Ocean, where it forms a vast delta known as the Sundarbans. This delta is one of the largest mangrove forests in the world and is home to a diverse range of flora and fauna, including the Bengal tiger.
Understanding the flow of the Ganges River is essential for comprehending the geographical and cultural landscape of India and Bengal. The river's journey from the Himalayas to the Bay of Bengal highlights its importance not only as a geographical feature but also as a cultural and religious symbol. The Ganges is often referred to as the "Ganga Maiya" or "Mother Ganga" in Hinduism, emphasizing its revered status in Indian culture.
In contrast, the other options provided do not fit the description given in the question. The Caspian Sea, while a significant body of water, is a lake located between Europe and Asia and does not flow through India or Bengal. The Yellow Sea is a marginal sea of the Pacific Ocean located between China and the Korean Peninsula, and Lake Baikal is a freshwater lake in Russia, neither of which are rivers flowing into the Bay of Bengal.
Thus, the Ganges River is the correct answer as it is the only river among the options that flows through India and Bengal and ends its journey in the Bay of Bengal.
