The correct answer is Option 3: Both 1 and 2.
1. Ajman is one of the seven Emirates of the UAE: This statement is correct. The United Arab Emirates (UAE) is made up of seven emirates, namely Abu Dhabi, Dubai, Sharjah, Ajman, Umm Al Quwain, Ras Al Khaimah, and Fujairah. Each emirate has its own ruler, and they collectively form the UAE. Ajman is one of these seven emirates and is located on the coast of the Arabian Gulf.
2. Ras al-Khaimah was the last Sheikhdom to join the UAE: This statement is also correct. Ras al-Khaimah was the last emirate to join the UAE. Initially, the UAE was established in 1971 with the joining of six emirates: Abu Dhabi, Dubai, Sharjah, Ajman, Umm Al Quwain, and Fujairah. Ras al-Khaimah joined the UAE on 10 February 1972, completing the formation of the federation. Before joining the UAE, Ras al-Khaimah was a separate sheikhdom.
It`s worth mentioning that the formation of the UAE involved negotiations and discussions among the emirates, and Ras al-Khaimah`s decision to join the federation came slightly later than the initial formation. However, it ultimately joined and became the seventh emirate of the UAE.
Therefore, both statements are correct, and the correct answer is Option 3: Both 1 and 2.
