Task: Answer the multiple-choice question.
Query: Which drug has a 1.865\% 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=C(NCC(c1cccs1)N1CCOCC1)c1cn(-c2ccccc2)nc1-c1ccc(F)cc1
b. C/C(=N\NC(=O)c1c[nH]c2ccccc12)c1ccc(C)o1
c. CCN(c1ccccc1)S(=O)(=O)c1ccc(C(=O)Nc2ncccc2O)cc1
d. Cc1ccc(NC(=O)CSc2n[nH]c(C)c2[N+](=O)[O-])cc1
Answer: b. C/C(=N\NC(=O)c1c[nH]c2ccccc12)c1ccc(C)o1
