○ with chemicals on it

Explanation:

First Question (What destroys the Golden Gate Bridge and half of San Francisco?):

The Golden Gate Bridge is in a region prone to earthquakes (San Francisco is on the San Andreas Fault). Earthquakes are seismic events that can cause structural damage to bridges and urban areas. Microwave radiation from the sun doesn't cause such localized destruction, lightning is too localized, and tornadoes are rare in San Francisco's climate.

In sci - fi or geological disaster - related narratives (like attempts to restart the Earth's core), detonating nuclear explosions is a common fictional method to induce large - scale geological changes. Using a large magnet, dropping from a ship, or using chemicals are less likely methods for such a high - stakes, large - scale core - related attempt.

Answer:

B. earthquakes
