Problem statement: Answer the multiple choice question.
Question: Which drug has a -0.380\% 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.) CCCCN(C(=O)CSc1c(C)c(C)cc(C)c1C)c1c(N)n(CCC)c(=O)[nH]c1=O
b.) CCN(CC)S(=O)(=O)c1cc(C(=O)N=c2sccn2C)ccc1OC
c.) COc1cc(C(=O)OCC(=O)N(CC(C)C)C2CCS(=O)(=O)C2)cc(OC)c1C
d.) CCn1cc(C(=O)O)c(=O)c2cc(Br)ccc21
Answer: d. CCn1cc(C(=O)O)c(=O)c2cc(Br)ccc21
