Task: Answer the multiple choice question.
Query: Which compound exhibits a 4.107\% 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 other words.
Options:
a: O=C(O)Cn1c(SCc2ccccc2)nc2ccccc21
b: Cc1cc2nn(-c3ccccc3)nc2cc1NC(=O)c1cccs1
c: C=CCNC(=O)CNS(=O)(=O)c1ccc(F)cc1
d: CCOC(=O)c1ccc2c(c1)N(C)C(=O)c1ccccc1S2
e: COc1ccc(/C=C/C(=O)c2cc(Br)ccc(=O)c2O)cc1
Answer: a. O=C(O)Cn1c(SCc2ccccc2)nc2ccccc21
