Task: Answer the multiple-choice question.
Query: Which drug has a 7.889\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
a.) COc1ccc(-c2cc3c(nn2)-c2ccccc2C3=O)cc1
b.) S=C(NCCCn1ccnc1)Nc1ccc(Cl)cc1Cl
c.) CCCc1ccc(C(C)NC(=S)NCc2ccc(F)cc2)cc1
d.) O=C(c1cc([N+](=O)[O-])ccc1N1CCCC1)N1CCCCC1
Answer: a. COc1ccc(-c2cc3c(nn2)-c2ccccc2C3=O)cc1
