Problem statement: Answer the multiple choice question.
Question: Which compound has a 12.383\% 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, or c without using any other words.
Options:
a: O=c1oc2ccccc2cc1-c1ccc(O)cc1O
b: O=C(c1ccncc1)N(Cc1ccccc1)Cc1nc2ccccc2c(=O)[nH]1
c: COc1cc(OC)c2ccc(=O)oc2c1C(CCN1CCCCC1)c1ccc(N(C)C)cc1
Answer: a. O=c1oc2ccccc2cc1-c1ccc(O)cc1O
