Task: Answer the multiple choice question.
Question: Which drug has a 2.142\% 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, or c without using any other words.
Options:
a O=C(NCCN1CCOCC1)c1ccc2c(c1)N(Cc1ccccc1)CCS2
b Cc1ccc(Cl)cc1NC(=O)NCc1cccnc1
c N#C/C(=C\c1c(N2CCCCCC2)nc2ccccn2c1=O)C(=O)NCc1ccco1
Answer: c. N#C/C(=C\c1c(N2CCCCCC2)nc2ccccn2c1=O)C(=O)NCc1ccco1
