Problem statement: Answer the multiple choice question.
Query: Which drug has a -7.900\% 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=C(c1cccs1)N1CCN(C(=O)C(c2ccccc2)c2ccccc2)CC1
[b] CN1/C(=C\C=C2/C(=O)Oc3ccccc3C2=O)C(C)(C)c2ccccc21
[c] O=C(CCCn1c(=O)[nH]c2cc(Cl)ccc2c1=O)NCC1CCCO1
Answer: a. O=C(c1cccs1)N1CCN(C(=O)C(c2ccccc2)c2ccccc2)CC1
