The South China Sea Dispute involves which of the following countries? 1. China 2. Vietnam 3. Malaysia 4. Indonesia Select the correct answer using the code given below.

The South China Sea dispute involves multiple sovereign states with overlapping territorial and maritime claims. China asserts expansive sovereignty over nearly the entire sea via its 'nine-dash line' [2]. Vietnam claims the Paracel and Spratly Islands based on historical discovery and occupation [1]. Malaysia claims several features in the Spratly Islands that fall within its Exclusive Economic Zone (EEZ) as defined by UNCLOS [2]. While Indonesia is often listed as a party to the broader regional tensions due to China's claims overlapping with Indonesia's EEZ near the Natuna Islands [2], it is technically a non-claimant to the disputed land features (islands/reefs) themselves [1]. Standard UPSC-style interpretations of 'claimant states' in the core dispute typically focus on China, Vietnam, Malaysia, the Philippines, Brunei, and Taiwan. Therefore, China, Vietnam, and Malaysia are primary parties to the dispute.
