Task: Answer the multiple choice question.
Question: Which drug exhibits a 0.588\% 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(c1ccccc1NS(=O)(=O)c1ccc(F)cc1)N1CCCC1
b) O=c1[nH]cc(NCCN2CCN(c3ncc(C(F)(F)F)cc3Cl)CC2)c(=O)[nH]1
c) COc1ccc(CNC(=O)C(c2ccncc2)N(C(=O)Cc2cccs2)c2ccccc2C)cc1
d) CNC(=O)CCCCC(=O)N/N=C/c1ccc(Cl)cc1Cl
e) Cc1ccc(OCC(=O)N(C)CC(=O)Nc2cccc(F)c2)cc1
Answer: b. O=c1[nH]cc(NCCN2CCN(c3ncc(C(F)(F)F)cc3Cl)CC2)c(=O)[nH]1
