Problem statement: Answer the multiple choice question.
Question: Which compound exhibits a 4.534\% 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: O=C(c1ccc(CSc2ccccc2)cc1)N1CCCCCC1
b: C=CCn1c(NCCO)nc2c1c(=O)n(C)c(=O)n2C
c: CCC(C)n1[nH]c(=O)cc1N
d: O=C(c1ccccc1-c1nc2ccccc2[nH]1)N1CCOCC1
e: CCOC(=O)N1CCN(C(=O)c2ccccc2-c2ccccc2)CC1
Answer: d. O=C(c1ccccc1-c1nc2ccccc2[nH]1)N1CCOCC1
