Explanations:The question asks to identify an Indian state based on two key characteristics: the presence of wide and deep rivers, and the practice of children using trolleys to cross these rivers to go to school. These specific features are most closely associated with Jammu & Kashmir.
Jammu & Kashmir is a state in northern India, known for its diverse geography, which includes the Himalayan mountain range and several major rivers. The rivers in Jammu & Kashmir, such as the Jhelum and the Chenab, are indeed wide and deep, making them significant geographical features of the region. The state's topography and the presence of these rivers have led to unique cultural practices and transportation methods.
One such practice is the use of trolleys to cross rivers. In some areas of Jammu & Kashmir, particularly in rural and remote regions, children have to cross rivers to reach their schools. Due to the depth and width of these rivers, traditional bridges may not be feasible, and thus, trolleys or similar river-crossing devices are used. This method of transportation is a practical solution to the geographical challenges posed by the rivers.
Other states mentioned in the options, such as Kerala and Tamil Nadu, do not share these specific characteristics. Kerala is known for its backwaters and canals, but it does not have the wide and deep rivers described in the question, nor is it common for children to use trolleys to cross rivers to go to school. Similarly, Tamil Nadu does not have the wide and deep rivers described, and the practice of using trolleys to cross rivers is not common there.
Therefore, the correct answer is Jammu & Kashmir, as it is the only state that matches the description given in the question.
