Which one of these four teas is not a black tea?

oops for someone who drinks as much tea as I do I should have got that right, but I didn't

Do more research

Sorry, but the answer options are incorrect .. as bigmackdaddie quite rightly points out, Darjeeling tea can be green white and oolong.

Sorry, but Darjeeling can be green, white or oolong ... a pity, but the answer options are incorrect.

apparently you cannot drink green tea when you are having chemotherapy

Love all teas

Only drink Yorkshire tea. With a sausage and egg sarnie and plenty of HP brown sauce.

Green tea is an anagram of generate.

No idea I don’t drink tea !

darjeeling is know as a white tea too, and so your answer is wrong or maybe a bad question.

Darjeeling white tea Darjeeling tea is a tea grown in the Darjeeling district in West Bengal, India, and widely exported and known. It is processed as black, green, white and oolong tea. When properly brewed, it yields a thin-bodied, light-coloured infusion with a floral aroma.

Green tea is b****y awful--especially when served in Chinese jam-jar!

Not bad for someone who only knows about sweet tea (typical Southerner)

Darjeeling is sometimes processed as a green or white tea. So, some darjeeling teas are not considered black teas.

guessed, but guessed well
