Which idiom refers to self-promotion or boasting?

• A. Nagbuhat ng sariling bangko.
• B. Utak-biya.
• C. Namamangka sa dalawang ilog.
• D. Taingang-kawali.

Answer: (A)

Self-promotion through bragging is conveyed by nagbuhat ng sariling bangko. It uses a vivid image—lifting one’s own bench—as a metaphor for claiming credit or presenting oneself as superior, often to boast about one’s status or achievements. When this phrase is used, it signals that someone is talking themselves up or showing off. The other expressions describe different behaviors: namamangka sa dalawang ilog means trying to please two sides, taingang-kawali refers to someone who mostly listens, and utak-biya points to clever or crafty thinking. So this idiom best captures boasting about oneself.
