Task: Answer the multiple-choice question.
Query: Which drug exhibits a 9.600\% 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(NC1CCCCCCC1)C1CCCN(S(=O)(=O)c2cnc[nH]2)C1
b. CCCCCOC(=O)Cn1c(=O)c2c(nc(N3CCOCC3)n2C)n(C)c1=O
c. Cc1cc(C(=O)N/N=C/c2ccc(OCc3ccccc3)cc2)c(C)o1
d. O=C(N/N=C/c1cn(-c2ccccc2)nc1-c1ccc([N+](=O)[O-])cc1)c1ccncc1
Answer: d. O=C(N/N=C/c1cn(-c2ccccc2)nc1-c1ccc([N+](=O)[O-])cc1)c1ccncc1
