Problem statement: Answer the multiple choice question.
Question: Which drug exhibits a 4.806\% 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: CC#CCN1c2ccccc2[C@]23C[C@@H](C(=O)OC)N(C(=O)c4ccco4)C2=NC(C(=O)OC)=C(C(=O)OC)[C@H]13
b: CC1(C)Cc2nc(NC3CCCCC3)c(C#N)cc2CO1
c: CCOC(=O)c1ccc[n+](CC(=O)Nc2cc(C(F)(F)F)ccc2Cl)c1.[Cl-]
d: CSCCC(NC(=O)c1ccccc1Cl)C(=O)N1CCCCCCC1
e: Cc1cc(C(=O)OCC(=O)c2ccc(Br)s2)no1
Answer: b. CC1(C)Cc2nc(NC3CCCCC3)c(C#N)cc2CO1
