Task: Answer the multiple-choice question.
Question: Which drug has a 13.601\% 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=C1NN(c2cccc(Br)c2)C(=O)/C1=C/c1ccc(-c2cc([N+](=O)[O-])ccc2O)o1
b. NCCN=C1NS(=O)(=O)c2ccccc21
c. CCOC(=O)C1CCN(C(=O)c2cccc(N3C(=O)NC4CC3(C)Oc3ccc(C)cc34)c2)CC1
d. CC1=CC(C)(C)N(C(=O)CSc2nnc(N)s2)c2cc(C)c(C)cc21
Answer: b. NCCN=C1NS(=O)(=O)c2ccccc21
