Problem statement: Answer the multiple choice question.
Query: Which compound has a 20.163\% 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, or d without using any other words.
Options:
a O=C(CC(c1ccccc1)c1ccccc1O)NCCc1ccccc1
b N#C/C(=C\C=C\c1ccccc1)c1nc(-c2ccc3c(c2)OCO3)cs1
c O=C(O)CN1C(=O)/C(=C\c2cc(Br)ccc2OCc2ccc(Cl)cc2Cl)SC1=S
d Cc1ccc(C(=O)NCC(=O)Nc2cccc(C(F)(F)F)c2)cc1
Answer: a. O=C(CC(c1ccccc1)c1ccccc1O)NCCc1ccccc1
