Anthropic's public research blog focused on AI alignment and safety research.

• A. Alignment Science Blog
• B. Frontier Red Team Blog
• C. RLHF (Reinforcement Learning from Human Feedback)
• D. Responsible Scaling Policy

Answer: (A)

The name of Anthropic's public research blog focused on AI alignment and safety research is Alignment Science Blog. This is the official outlet where Anthropic shares research progress, methodological work, and discussions about alignment challenges and safety considerations in AI. The other options refer to different things: Frontier Red Team Blog suggests a red-teaming focus, RLHF stands for Reinforcement Learning from Human Feedback and is a training approach rather than a blog title, and Responsible Scaling Policy sounds like a policy document rather than a blog name. Alignment Science Blog matches both the topic focus and the naming style Anthropic uses for its public research content.
