Task: Answer the multiple choice question.
Question: Which compound exhibits a 19.068\% 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 CCCCCN(C(=O)CCCSc1nncs1)c1c(N)n(CCCC)c(=O)[nH]c1=O
b O=C(CSc1ccccn1)Nc1nc2ccccc2s1
c O=C(Nc1ccccn1)C1(c2ccccc2)CCCC1
d CC(C)c1ccccc1NC(=O)CN1C(=O)c2ccccc2C1=O
Answer: a. CCCCCN(C(=O)CCCSc1nncs1)c1c(N)n(CCCC)c(=O)[nH]c1=O
