Task: Answer the multiple choice question.
Question: Which compound has a 1.395\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any other words.
Options:
a. COc1ccc(S(=O)(=O)NCC2CCCN(Cc3ccccc3Cl)C2)cc1
b. O=C1/C(=C/c2ccc(C(=O)O)cc2)CCC/C1=C\c1ccc(C(=O)O)cc1
c. CCN(CC)c1ccc2cc(C(C)=O)c(=O)oc2c1
d. O=C(Nc1ccc(Cc2ccncc2)cc1)c1cc([N+](=O)[O-])ccc1N1CCOCC1
e. COCCCn1c(=O)cc(C)[nH]c1=S
Answer: c. CCN(CC)c1ccc2cc(C(C)=O)c(=O)oc2c1
