Problem statement: Answer the multiple choice question.
Query: Which drug has a 2.169\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any additional words.
Options:
(a) Cc1ccc(/C=C/C(=O)Nc2ncc(C)s2)o1
(b) Cc1ccc(-c2cn(C[C@H]3CC[C@@H]([C@@H]4CC[C@H](Cn5cc(-c6ccc(C)cc6)nn5)O4)O3)nn2)cc1
(c) Cc1ccc(NC(=S)N(Cc2cccc(Br)c2)CC2CCC(C(=O)O)CC2)cc1
(d) [N-]=[N+]=NC[C@H](Cc1ccccc1)N1CCN(Cc2ccccc2)CCC1=O
Answer: c. Cc1ccc(NC(=S)N(Cc2cccc(Br)c2)CC2CCC(C(=O)O)CC2)cc1
