Task: Answer the multiple-choice question.
Query: Which drug exhibits a -1.000% human ether-à-go-go related gene (hERG) inhibition at 10uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
a: O=C(Nc1cc2c(oc1=O)CCCC2=O)c1ccccc1
b: CCC(C)(C(=O)NC1CCCCC1)N(Cc1cccs1)C(=O)CC1NC(=O)NC1=O
c: CCc1ccccc1NCC(=O)Nc1ccccc1C(=O)OC
d: COc1ccc(/C=C2\Oc3cc(OC(=O)N4CCOCC4)ccc3C2=O)c(OC)c1
Answer: b. CCC(C)(C(=O)NC1CCCCC1)N(Cc1cccs1)C(=O)CC1NC(=O)NC1=O
