The complex molecule that triggers an immune response is an Antigen.

Here's a step-by-step explanation:

1. An antigen is a substance that the immune system identifies as foreign or potentially harmful.

2. The immune system recognizes the antigen as a threat and responds by producing specific proteins called antibodies.

3. These antibodies bind to the antigen to neutralize it, mark it for destruction, or signal other immune cells to destroy it.

4. This process is part of the body's immune response, which helps protect against infections and diseases.

So, the correct answer is Antigen.
