B, Redundancy<span> is the grammatical error in the title. Using the words 'relationship between' and 'correlation' is redundant/unnecessarily repetitive. (Correlation is a mutual relationship or connection between two or more things).</span>
Cool! Need help with any questions?
Actually, the correct sentence is the following one "You are much more logical than I".
Think about it as if it was a short version of the sentence
"You are much more logical than I am".: here you couldn't say
"You are much more logical than me am". that's why you also should not say it in the shorter version.
