Problem statement: Answer the multiple-choice question.
Query: Which drug has a 6.684\% 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, c, or d without using any other words.
Options:
a: CCC(Nc1nc(-c2ccccc2)nc2ccccc12)C(=O)O.Cl
b: Cc1cccc(C)c1N1CCN(CCn2c(=S)[nH]c3ccccc3c2=O)CC1
c: CCOc1cc(/C=N/NC(=O)CSc2cccc3cccnc23)ccc1O
d: CCOC(=O)c1ccc(NC(=O)c2nc[nH]c2C(=O)N(CC)CC)cc1
Answer: a. CCC(Nc1nc(-c2ccccc2)nc2ccccc12)C(=O)O.Cl
