Problem statement: Answer the multiple choice question.
Question: Which drug exhibits a 1.445\% 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) O=c1[nH]c(Cc2ccccn2)nc2scc(-c3ccccc3Cl)c12
(b) O=C(/C=C\Nc1ccc2c(c1)OCO2)c1cccs1
(c) C/C=C/c1ccc(OC(C)=O)c(OC)c1
(d) Cc1ccc(S(=O)(=O)N(Cc2cccc(F)c2)C(=O)N2CCN(C)CC2)cc1
Answer: a. O=c1[nH]c(Cc2ccccn2)nc2scc(-c3ccccc3Cl)c12
