Task: Answer the multiple choice question.
Query: Which drug exhibits a 0.571\% human ether-à-go-go related gene (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 COc1ccc(OC)c(-n2c(-c3ccc(C)cc3)n[nH]c2=S)c1
b CCC(C)Nc1nc2c(c(=O)n(C)c(=O)n2C)n1Cc1cccc(C)c1
c CCN(CC)C(=O)c1cc2cc([N+](=O)[O-])ccc2s1
d Cc1cccc2cc(C(c3nnnn3CC3CCCO3)N3CCCc4ccccc43)c(=O)[nH]c12
Answer: a. COc1ccc(OC)c(-n2c(-c3ccc(C)cc3)n[nH]c2=S)c1
