Task: Answer the multiple-choice question.
Question: Which drug exhibits a 6.502\% 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 additional words.
Options:
(a) COc1ccc(CNC(=S)NC2CCCC2)cc1
(b) C=CCn1c(SCc2ccc(C(=O)NCCO)cc2)nc2sc(C)c(C)c2c1=O
(c) C/C(=N/NC(=O)Cc1c(C)[nH][nH]c1=O)c1ccc(O)cc1
(d) COc1ccc2c(c1)OC[C@H]1[C@@H]2N2C(=O)CNC(=O)[C@@]2(C)[C@H]1c1ccccc1
(e) O=C(NNC(=O)c1ccc2c(=O)n3c(nc2c1)CCC3)c1ccc(Cl)cc1
Answer: e. O=C(NNC(=O)c1ccc2c(=O)n3c(nc2c1)CCC3)c1ccc(Cl)cc1
