The correct answer is option 'D'.

In Saudi Arabia, the political system is characterized by a monarchy with a unique combination of Islamic law and traditional customs. While the king holds significant power and influence, there are certain aspects of the political system that do not align with option 'D'. Let's explore each option in detail:

a) The king selects the executive, legislature, and judiciary:
In Saudi Arabia, the king does hold significant power and authority. The king is responsible for appointing key positions within the executive branch, including the prime minister and members of the cabinet. However, it is important to note that the king does not personally select every member of the legislature and judiciary. The king appoints members of the Consultative Assembly, also known as the Shura Council, but the assembly also includes elected representatives. The judiciary, although subject to the king's influence, operates independently and has its own hierarchical structure.

b) Citizens cannot form political parties:
This statement is true. The Saudi Arabian political system does not allow for the formation of political parties. Instead, political participation is channeled through other means, such as tribal affiliations, religious groups, or informal networks. This system is designed to maintain stability and prevent the emergence of organized political opposition.

c) There is no freedom of religion:
This statement is also true. In Saudi Arabia, the official religion is Islam, and the country follows a strict interpretation of Sunni Islam known as Wahhabism. While the government does tolerate other religions to some extent, the practice of non-Muslim religions is heavily regulated and restricted. Non-Muslim religious activities are generally conducted privately, and public worship or proselytizing is not allowed. The government enforces Islamic law, which governs many aspects of daily life, including religious practices.

In conclusion, the correct answer is option 'D' because both options 'a' and 'c' contain elements that are accurate in describing the Saudi Arabian political system. However, option 'b' is correct as citizens in Saudi Arabia cannot form political parties.
