Problem statement: Answer the multiple choice question.
Question: Which drug exhibits a -21.385\% 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 other words.
Options:
a.) O=C(c1cc(-c2ccc(Cl)cc2)nc2ccccc12)N1CCC1
b.) N#C/C(=C\c1ccncc1)C(=O)Nc1ccc(C(=O)O)cc1
c.) COc1cc(NS(=O)(=O)c2c(C)[nH]c(C)c2C(=O)N2CCCC2)cc(OC)c1OC
d.) Cc1ccc(/C(O)=C/c2nc3ccccc3oc2=O)cc1
e.) Nc1nc(SCC(=O)c2cccs2)n[nH]1
Answer: a. O=C(c1cc(-c2ccc(Cl)cc2)nc2ccccc12)N1CCC1
