Task: Answer the multiple-choice question.
Query: Which drug exhibits a 8.080\% 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) CC1(C)Cc2c(c(N3CCCC3)[nH]c(=S)c2C#N)CO1
(b) C/C=C(\C)c1nnc(NC(=O)OCC)s1
(c) CCc1ccc2[nH]c(=O)c(C(c3nnnn3CC3CCCO3)N3CCCc4ccccc43)cc2c1
(d) COC(=O)c1cn(NC(=O)c2cccc(OC)c2)c(=O)c2ccccc12
(e) S=c1[nH]nc(-c2ccncc2)n1Cc1ccccc1
Answer: a. CC1(C)Cc2c(c(N3CCCC3)[nH]c(=S)c2C#N)CO1
