Problem statement: Answer the multiple choice question.
Question: Which drug exhibits a 0.308\% 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.) COc1cccc(NC(=O)Nc2cc(C)ccc2OC)c1
b.) CCOc1cc(C2C(C(=O)O)c3cc(OCC)c(OCC)cc3C(=O)N2C)ccc1O
c.) C=CCN=C1CC(C)(C)CC(=O)/C1=C(\O)c1ccccc1
d.) Cc1cc(C(C)(C)C)ccc1OCCn1ccnc1.O=C(O)C(=O)O
e.) O=C(CSc1ncc(-c2ccc(F)cc2)n1Cc1ccco1)Nc1nccs1
Answer: c. C=CCN=C1CC(C)(C)CC(=O)/C1=C(\O)c1ccccc1
