Explanation: Gaurav Jani is a well-known Indian long-distance walker who has undertaken several significant journeys across India. One of his notable journeys started from Mumbai, the capital city of Maharashtra, and lasted for a period of 2 months. This journey is a significant event in the context of Indian geography and travel, as it highlights the endurance and dedication required for such long-distance walking expeditions.
The question tests the understanding of time duration in the context of a long journey. It is important to note that the journey is described as a "long journey," which implies a significant amount of time. The options provided include units of time (months) and distance (miles, kilometers). The correct answer must reflect a realistic time frame for a long-distance walking expedition.
Option A (2.5 months) is close to the correct answer but slightly overestimates the duration. Option B (2 miles) and Option D (2 kilometers) are incorrect because they use units of distance instead of time. Miles and kilometers are units used to measure the length of a journey, not the duration. The correct answer, Option C (2 months), accurately reflects the time duration of Gaurav Jani's journey from Mumbai.
Understanding the context of the journey is crucial. Gaurav Jani's expeditions are known for their length and the physical and mental endurance required to complete them. A 2-month journey is a realistic and commonly cited duration for such a walking expedition, making it the correct answer.
In summary, the question tests the ability to identify the correct unit of measurement (time) and the realistic duration of a long-distance walking journey. The correct answer, 2 months, is consistent with the known facts about Gaurav Jani's expeditions and the context of the question.
