(B) Yemenis first drank coffee to help themselves focus on God  

This statement is TRUE.

Explanation:

The coffee was first cultivated in 'Yemen' and Yemenis gave it an Arabic name 'qahwa'. Coffee and café are derived from this name. It was drunk in the Sufi communities of Yemen. Monks used to drink it to remain focused during their nighttime prayers or during the time they used to pray for a long time.

It is believed that coffee originated in Mecca in 1414. Then around 1500s it started spreading to "Egypt" from the "Yemeni port of Mocha".

Coffee houses became  a popular place where men gathered to meet each other, listen to poets and used to play games. Also, coffee houses became the center for intellectual life.
