Task: Answer the multiple-choice question.
Question: Which compound exhibits a 6.564\% 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 additional words.
Options:
a) O=S(=O)(c1ccc(Cl)cc1)c1cc(O)ccc1O
b) Cc1cc2c(NC(=O)CCCC(=O)O)cccc2nn1
c) Cc1ccc(C(=O)NC(=S)NNC(=O)c2ccccc2O)cc1
d) CCCCn1c(N)c(Br)c(=O)[nH]c1=O
Answer: d. CCCCn1c(N)c(Br)c(=O)[nH]c1=O
