Problem statement: Answer the multiple-choice question.
Query: Which drug exhibits a -1.212\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
a) Oc1cc(O)c2c(c1)O[C@H](c1ccc(O)c(O)c1)[C@H](O)C2
b) Cc1nn(-c2ccccc2)c(N2CCCC2)c1C=O
c) CCSC1=N/C(=C\c2ccc3c(c2)OCO3)C(=O)S1
Answer: a. Oc1cc(O)c2c(c1)O[C@H](c1ccc(O)c(O)c1)[C@H](O)C2
