Problem statement: Answer the multiple-choice question.
Question: Which compound has a -0.514\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
[a] COCc1nc2ccccc2n1Cc1ccccc1Br
[b] O=C(O)c1ccc2c(=O)[nH]c(CN3CCOCC3)nc2c1
[c] O=C(NCC1CCCCC1)c1cccc(Br)c1
[d] CSCCC(NC(=O)c1ccco1)C(=O)N1CC=C(c2ccccc2)CC1
Answer: c. O=C(NCC1CCCCC1)c1cccc(Br)c1
