Problem statement: Answer the multiple choice question.
Question: Which drug has a 9.994\% 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 other words.
Options:
a) COc1ccc(/C(C)=N/NC(=O)CNC(=O)/C=C\c2ccccc2OC)c(OC)c1
b) Cc1ccc(C(=O)NCC(c2ccc(F)cc2)N2CCOCC2)cc1
c) O=C(c1nnc(-c2ccncc2)o1)c1ccccc1Cl
d) COc1ccc(CCNC(=O)[C@H](CC(C)C)NC(=O)N2CCn3c2nc2ccccc23)cc1OC
Answer: c. O=C(c1nnc(-c2ccncc2)o1)c1ccccc1Cl
