I have been working on this and am still confused. Which sentence is correct. Using the pronoun case-

A) My brother knows more about technology than me.
B) My brother knows more about technology than I.

I thought it would be best for B and add to it the word do at the end but we are given these two sentences so as written I now think the correct answer is A. Could this be correct.

No, B is correct.
For sentence B, we understand that it means "than I do." You can add "do" if you want.
