Task: Answer the multiple-choice question.
Question: Which drug exhibits a 7.887\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any additional words.
Options:
a.) O=C(N/N=C/c1c[nH]c2c1ccc1ccccc12)c1ccc([N+](=O)[O-])cc1
b.) C=CCOC(=O)C1=C[C@H](c2ccc(C(F)(F)F)cc2)[C@@H](CCCO)[C@H](OCC)O1
c.) Cc1noc(/C=C/c2ccco2)c1S(=O)(=O)N1CCC(C(=O)N2CCc3ccccc32)CC1
d.) CN(Cc1cn(C)nc1-c1cccc(Cl)c1)CC1CCCCO1
e.) CC[N+](C)(CC)CCC/C(=N/O)C(O)(c1ccccc1)c1ccccc1.[I-]
Answer: a. O=C(N/N=C/c1c[nH]c2c1ccc1ccccc12)c1ccc([N+](=O)[O-])cc1
