Problem statement: Answer the multiple choice question.
Question: Which drug exhibits a 9.277\% 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=C(NC1CCCC1)c1ncn[nH]1
(b) Fc1ccccc1Cc1noc(CN2CCCC(CN3CCOCC3)C2)n1
(c) Cc1cc([N+](=O)[O-])cc2ncccc12
(d) CCCCN(CC)CCCNC(=O)c1cn(C)c(=O)c2c1c1ccccc1n2C
Answer: a. O=C(NC1CCCC1)c1ncn[nH]1
