Task: Answer the multiple-choice question.
Question: Which compound exhibits a -4.766\% human ether-à-go-go related gene (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(NCc1cccnc1)/C(=C/c1ccc(-c2cccc(Cl)c2)o1)S(=O)(=O)c1ccccc1
b: O=C(Cc1cccs1)Nc1nc(-c2ccc(F)cc2F)cs1
c: CCn1c(N)c(C(=O)NCc2ccc3c(c2)OCO3)sc1=S
d: CCCN1CCC(NC(=O)C2CC=CCC2C(=O)O)CC1
e: Nc1nnc(SCC(=O)NNC(=O)c2ccc(F)cc2)s1
Answer: a. O=C(NCc1cccnc1)/C(=C/c1ccc(-c2cccc(Cl)c2)o1)S(=O)(=O)c1ccccc1
