Which of the following search engines is not multilingual?

Multilingual Search Engines: Search engines like Google, Bing, and Yahoo! are global platforms that support, index, and provide user interfaces in dozens of different languages (multilingual). They serve a worldwide audience.

• Baidu: Baidu is China's dominant search engine. It is explicitly designed and optimized for the Chinese language (Simplified Chinese) and primarily caters to the domestic Chinese market. Unlike Google or Bing, it does not offer a widespread multilingual interface or global multi-language search optimization, making it monolingual by comparison.
