The Philippines is the ____ signatory to the Stockholm Convention.

• A. 50th
• B. 51st
• C. 52nd
• D. 53rd

Answer: (B)

The main idea here is understanding what it means to be a signatory to an international treaty and how the order of signing works. A signatory is a state that has signed the treaty to show intent to be bound in the future; this is separate from becoming a party, which happens after ratification or accession.

Being the 51st signatory means the Philippines signed the Stockholm Convention after fifty other states had already signed. This reflects the sequence of signing, not necessarily any later legal obligations, which only come into play once the country ratifies or accedes and becomes a party. So the Philippines’ position as the 51st signatory correctly places it in that signing order.

The other options would place the signing in different positions in the sequence, which doesn’t align with the record of when the Philippines signed.
