Task: Answer the multiple-choice question.
Query: Which drug exhibits a 3.150\% 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. COc1cccc(N=c2oc3ccc(OC)cc3cc2-c2nc3ccccc3[nH]2)c1
b. CCCCCCc1cc2cc(C(=O)Nc3ccc(OC)cc3)c(=O)oc2cc1O
c. COc1cc(C(=O)NC2CCCC(C)C2C)ccc1OCC(=O)N1CCOCC1
