Task: Answer the multiple choice question.
Question: Which drug exhibits a 19.758\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any additional words.
Options:
a Cn1c(=O)c2c(ncn2CC(=O)Nc2nnc(Cc3ccccc3)s2)n(C)c1=O
b O=C(NCCN1CCOCC1)c1cc(=O)[nH]c2ccc(Br)cc12
c Cc1ccc(CNC(=O)CCS(=O)(=O)c2ccc3c(c2)NC(=O)CO3)cc1
d CCCCc1ccc(CC2S/C(=C(\C#N)C(=O)N3CCOCC3)N(c3ccccc3)C2=O)cc1
e O=C1c2ccccc2C(O)(Cc2ccccc2)N1C1CCCCC1
Answer: a. Cn1c(=O)c2c(ncn2CC(=O)Nc2nnc(Cc3ccccc3)s2)n(C)c1=O
