Task: Answer the multiple choice question.
Query: Which drug exhibits a -0.869\% 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 CC(C)N(CC#CCC(O)(c1ccccc1)C1CCCC1)CCO
b CN1/C(=C\C(=O)c2cccs2)C(C)(C)c2ccccc21
c CN(Cc1nccn1C)C(=O)CC1C(=O)NCCN1Cc1cccc(Oc2ccccc2)c1
Answer: a. CC(C)N(CC#CCC(O)(c1ccccc1)C1CCCC1)CCO
