Problem statement: Answer the multiple choice question.
Query: Which drug exhibits a -6.493\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any other words.
Options:
a: Cc1c(NC(=O)COC(=O)CCc2c[nH]c3ccccc23)c(=O)n(-c2ccccc2)n1C
b: COc1ccc2[nH]cc(CCNC(=O)Nc3ccccc3)c2c1
c: O=C(O)COc1ccc(-c2nccc(-c3cccs3)n2)cc1
d: CCN(CC)CCN1C(=O)c2oc3ccccc3c(=O)c2C1c1ccc(C)cc1
e: Cc1ccc(CNC(=O)CCSCc2ccc(C)cc2)cc1
Answer: d. CCN(CC)CCN1C(=O)c2oc3ccccc3c(=O)c2C1c1ccc(C)cc1
