Problem statement: Answer the multiple-choice question.
Query: Which drug exhibits a 15.164\% 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 other words.
Options:
a. O=c1cc(Cn2ccnc2)c2cc(O)ccc2o1
b. Cn1ccnc1SCC(=O)c1ccc(Br)cc1
c. O=C(c1ccc(C(F)(F)F)cc1)C1CCCN(C(=O)CCn2cncn2)C1
d. CCn1nc([N+](=O)[O-])c2c(-c3nc4ccccc4o3)c(N)n(CCCOC)c2c1=O
Answer: a. O=c1cc(Cn2ccnc2)c2cc(O)ccc2o1
