it sank the lusitania, which was carrying passengers to europe.
it attacked mexico for its support of the united states.
it refused to sell products to companies in the united states.
it sent a secret telegram to russia asking for an alliance.

Explanation:

To determine the correct answer, we analyze each option:

• The first option: In 1915, Germany sank the Lusitania, a British passenger liner with American passengers, which challenged U.S. neutrality.
• The second option: Germany did not attack Mexico for U.S. support; the Zimmermann Telegram (1917) proposed an alliance with Mexico against the U.S., not an attack.
• The third option: Germany’s actions in 1915 were not about refusing to sell products to U.S. companies.
• The fourth option: Germany’s 1915 actions did not involve a secret telegram to Russia for an alliance; the Zimmermann Telegram was to Mexico (1917).

So the correct event testing U.S. neutrality in 1915 is the sinking of the Lusitania.

Answer:

It sank the Lusitania, which was carrying passengers to Europe.
