Task: Answer the multiple-choice question.
Question: Which drug exhibits a 3.995\% 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, d, or e without using any additional words.
Options:
a CCOC(=O)c1c(N)sc2c1CCCC2
b CCc1ccc(-n2cnc3cc(C(=O)NCC(OC)OC)ccc32)cc1
c O=C(O)c1sccc1NC(=O)c1c(Cl)cccc1Cl
d Cc1cc(C)[n+](-c2ccc(C(C)C)cc2)c2[nH]c(=O)[nH]c(=O)c12.[I-]
e O=C(N/N=C(\Cc1ncc[nH]1)c1ccccc1)c1ccccc1
Answer: c. O=C(O)c1sccc1NC(=O)c1c(Cl)cccc1Cl
