Task: Answer the multiple choice question.
Question: Which drug exhibits a 12.666\% 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 additional words.
Options:
a: Cc1ccc2nc(C3CCCCC3)[nH]c2c1
b: Cc1cc(C(=O)N[C@H](c2ccccc2)[C@@]2(C)C[C@@H]2[C@@H](C)C(=O)Nc2ccc3ccccc3c2)n(C)n1
c: NC(=O)c1ccc(NC(=O)c2ccc3c(c2)OCO3)cc1
d: CCCCN(C(=O)c1cc2c(s1)CCCCC2)c1c(N)n(CCC)c(=O)[nH]c1=O
Answer: d. CCCCN(C(=O)c1cc2c(s1)CCCCC2)c1c(N)n(CCC)c(=O)[nH]c1=O
