Explanations:The question involves evaluating the accuracy of three statements related to Gujarat's geography, historical context, and agricultural production. Let's break down each statement:
1. "Mount Abu is the only hill station of Gujarat." This statement is incorrect. Mount Abu is actually located in Rajasthan, not Gujarat. It is a popular hill station known for its scenic beauty and the famous Dilwara Jain Temples. Gujarat does not have any hill stations of comparable significance.
2. "Gujarat, Oman, Swahili States, and Java were all non-European rivals of the Portuguese in the Indian Ocean." This statement is correct. During the 16th and 17th centuries, the Indian Ocean was a significant trade route, and various non-European powers competed with the Portuguese for control. Gujarat, with its strategic location and thriving ports like Surat, was a key player in this trade. Oman, the Swahili States (along the East African coast), and Java (in present-day Indonesia) were also important centers of trade and resistance against Portuguese dominance.
3. "Gujarat was the largest producer of groundnut in India." This statement is also correct. Gujarat has been the leading producer of groundnut (also known as peanuts) in India for many years. The state's favorable climate and soil conditions, along with the traditional cultivation practices, have made it a significant contributor to India's groundnut production.
By evaluating these statements, we can conclude that the correct answer is Option D, which states that only the second and third statements are true. The first statement is incorrect due to the geographical location of Mount Abu, while the second and third statements are accurate based on historical and current agricultural data.
