Task: Answer the multiple-choice question.
Question: Which drug exhibits a 2.665% human ether-à-go-go related gene (hERG) inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
a COCCN1C(=O)c2ccccc2C(C(=O)N2CCN(c3ccccc3)CC2)C1c1ccc(F)cc1
b O=C(N/N=C/c1ccccc1O)c1ccncc1
c COC(=O)CN(c1ccccc1OC)S(=O)(=O)c1ccccc1
d O=C(CSc1ccc(-c2cccs2)nn1)Nc1ccccc1
Answer: b. O=C(N/N=C/c1ccccc1O)c1ccncc1
