Task: Answer the multiple-choice question.
Query: Which compound has a 5.508\% 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. O=C(N/N=C(\c1ccccc1)c1cccnc1)C(O)(c1ccccc1)c1ccccc1
b. CC(C)NC(=O)c1ccc2c(c1)N(Cc1ccccc1)C(=O)C(C)(C)O2
c. O=C(O)CCCc1ccc2ccc3cccc4ccc1c2c34
d. O=C(c1nnc(-c2ccc(Cl)cc2)o1)C1CCCC1
Answer: d. O=C(c1nnc(-c2ccc(Cl)cc2)o1)C1CCCC1
