Task: Answer the multiple choice question.
Query: Which drug exhibits a 13.282\% 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) O=[N+]([O-])c1ccc(C2Oc3ccccc3C3CC(c4ccccc4)=NN32)s1
(b) CCCN(c1ccccc1C(=O)O)S(=O)(=O)c1ccc2c(c1)n(C)c(=O)n2C
(c) N#CC1=C(N)Nc2ncnn2C1c1ccccc1
(d) COc1ccccc1OCC(=O)Nc1ccc2c(c1)OCO2
Answer: b. CCCN(c1ccccc1C(=O)O)S(=O)(=O)c1ccc2c(c1)n(C)c(=O)n2C
