Task: Answer the multiple-choice question.
Question: Which drug exhibits a -26.172\% 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 additional words.
Options:
a) COCCNC(=O)c1c(N)n(/N=C/c2cccs2)c2nc3ccccc3nc12
b) CC(C)CN(C(=O)c1ccc([N+](=O)[O-])s1)c1c(N)n(Cc2ccccc2)c(=O)[nH]c1=O
c) COc1ccc(C(=O)C2CCCN(Cc3cccn3-c3ccccn3)C2)c(C)c1
d) Cl.c1ccc2c(c1)N1CCCN=C1N2CCN1CCCCC1
Answer: d. Cl.c1ccc2c(c1)N1CCCN=C1N2CCN1CCCCC1
