I think that the answer is A and B because in this case, R is clearly a negative number, because it’s below 0. So if we change the symbol in front of the R, it has to be positive. Let’s say R is -20. Negative R should be - - 20, which is + 20. So -R > 0. We and also say that -R = V because there are an equal number of bounds that separate R and V from 0, and since -R is the inverse of R, it has to be equal to V.
