Task: Answer the multiple choice question.
Query: Which drug exhibits a 15.565\% 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 other words.
Options:
(a) CC(C)Cn1c(N)c(C=O)c(=O)[nH]c1=O
(b) Cc1c(C)c(C)c(S(=O)(=O)Nc2ccc3[nH]c(=O)[nH]c3c2)c(C)c1C
(c) Cc1[nH]c2ccccc2c1C(=O)CN1CCCCC1CCO
(d) Cc1ccc(/C=N/NC(=O)Cn2nc(C)c([N+](=O)[O-])c2C)o1
Answer: b. Cc1c(C)c(C)c(S(=O)(=O)Nc2ccc3[nH]c(=O)[nH]c3c2)c(C)c1C
