Problem statement: Answer the multiple choice question.
Question: Which drug has a 2.513\% 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] O=C(OC(C(=O)NC1CCCC1)c1ccccn1)c1cccs1
[b] CC1=C/C(=C\c2ccc(Br)o2)C(=O)O1
[c] CC(C)(C)c1ccc(/C=C2\SC(=O)N(CCNC(=O)c3cccc(S(=O)(=O)N4CCOCC4)c3)C2=O)cc1
Answer: a. O=C(OC(C(=O)NC1CCCC1)c1ccccn1)c1cccs1
