Explanation: To understand the context of this question, we need to break down each statement and analyze its accuracy.
1. **Mount Abu is the only hill station of Gujarat**: This statement is incorrect. Mount Abu is not located in Gujarat; it is situated in Rajasthan. Gujarat does not have any hill stations of its own. The highest point in Gujarat is the Girnar Hills, but it is not considered a hill station in the traditional sense.
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 over trade routes and resources. Gujarat, with its strategic location and thriving ports like Surat, was a key player in this competition. 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 correct. Gujarat is known for its significant agricultural output, particularly in groundnut (peanut) production. The state's favorable climate and soil conditions make it ideal for growing groundnuts, and it consistently ranks as the top producer in India.
In summary, the correct answer is (D) Only 2, 3. 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 agricultural data. Understanding the geographical, historical, and agricultural contexts is crucial for correctly identifying the true statements in this question.
