Task: Answer the multiple choice question.
Question: Which compound exhibits a 20.139\% human ether-à-go-go related gene (hERG) inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any other words.
Options:
a. CN(C[C@H](Cc1ccccc1)N(CCN(CCc1ccccc1)N=O)N=O)N=O.[Na+]
b. COc1ccc2cc(C3=CCCCC3)ncc2c1
c. O=C(O)C1C2CCC(O2)C1C(=O)Nc1ccc(F)c(F)c1
d. O=C(CC1C(=O)NCCN1Cc1ccccc1C(F)(F)F)NCCN1CCCCC1=O
e. O=C(c1cccc(C(F)(F)F)c1)C1CCCN(Cc2cccn2-c2ccccn2)C1
Answer: c. O=C(O)C1C2CCC(O2)C1C(=O)Nc1ccc(F)c(F)c1
