Task: Answer the MCQ question.
Question: Which drug has a 1.540\% 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) O=C(Nc1cc(Cl)ccc1-n1cncn1)c1cc(S(=O)(=O)N2CCOCC2)ccc1F
(b) CC(=O)NC1C(Oc2ccc(C=O)cc2)OC(COC(C)=O)C(OC(C)=O)C1OC(C)=O
(c) CCCCN1C[C@H](Cc2ccccc2)[C@@H](CC(=O)Nc2ccccc2)C1=O
(d) Cc1ccc(C)c(NS(=O)(=O)c2ccc3[nH]c(=O)oc3c2)c1
(e) Cc1onc(-c2c(F)cccc2Cl)c1C(=O)Nc1sc2c(c1C(N)=O)CCC2
Answer: e. Cc1onc(-c2c(F)cccc2Cl)c1C(=O)Nc1sc2c(c1C(N)=O)CCC2
