am teaching
have taught
have been teaching
teaching
Answer is Right!
Answer is Wrong!
The correct answer is C. have been teaching.
The sentence is in the present perfect continuous tense, which is used to talk about an action that started in the past and continues to the present. In this case, the speaker has been teaching English online since July 2014, and they are still teaching English online now.
The other options are incorrect because they do not accurately reflect the meaning of the sentence. Option A, am teaching, is in the present tense, which would be used to talk about an action that is happening right now.
