When someone explained something to me and I understood the explanation, does it sound ok to reply "Understood."?
A: He will come late to the office today due to a delay of the train.
B: OK, understood.
A. Please ask Mr. XX about it because he's in charge of it.
B. Understood. Thanks.
As you can see, I assume a situation where A is not telling an order or an instruction, but more just information.
An English teacher told me that it might contain some negative implication that I have no other choices but to understand it as told. Do you agree?
And how about saying "I see." in the same contexts?
