What is the name of the Korean flag?

The name of the Korean flag is commonly recognized as "Taegeukgi." This name refers to the flag's symbolic elements: the central yin-yang symbol (taegeuk) and the four trigrams that represent the principles of movement and harmony. The spelling "Taegeukgi" is widely accepted and aligns with its representation in both Korean language and culture, reflecting the flag's rich heritage.

The other choices are variations that either misspell the name or do not conform to the standard terminology used to refer to the flag. For instance, "Taegukgi" is a different romanization that, while close, is not the most commonly used form in English. "Tae Kukgi" provides an incorrect space that doesn't adhere to the correct term. "Korean Banner" is a generic phrase that fails to capture the specific cultural and historical significance of the flag. Therefore, the answer you provided does not represent the correct term used to identify the national emblem of Korea.
