Task: Answer the multiple-choice question.
Question: Which drug exhibits a 3.351\% 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. CCCCN(Cc1cc2cc(OC)ccc2[nH]c1=O)C(=O)c1ccccn1
b. CC(C)(CO)NCc1ccccc1OCC(=O)Nc1ccccc1
c. O=C(CC1(O)C(=O)N(Cc2ccccc2)c2ccccc21)c1ccncc1
d. Cc1cc[n+](CC(=O)Nc2cc(C(F)(F)F)ccc2Cl)cc1.[Cl-]
e. COc1ccc(OC)c(NC(=O)c2ccccc2N(Cc2ccccc2)S(C)(=O)=O)c1
Answer: c. O=C(CC1(O)C(=O)N(Cc2ccccc2)c2ccccc21)c1ccncc1
