Draw out the monomer, maybe it'd help for you to picture it?

Try to establish the longest chain.

Always look for the longest carbon chain.

It's b and d and it's c because the longest chains is all the c in the middle there 6 of them so hexane and the short count to get to each CH3 is 2 and then 4

B and d

Sorry man i should have been clearer okay count 4 in the middle chain going from left to right and you will get to ethyl notice there are 2 carbons on the ethyl that mean the longest "chain of carbon" is hexane as it goes c-c-c-c in the middle then up 2 c-c in the ethyl to get the longest possible chain cool
