Task: Answer the multiple choice question.
Query: Which drug exhibits a 4.447\% 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) N#CN/C(=N\S(=O)(=O)c1ccccc1)c1ccccc1
b) COc1ccc(Cc2noc(-c3ccccc3)n2)cc1OC
c) C=CCNc1cc(C)oc(=O)c1C(=O)CC
d) Cc1cccc(N2CCN(C(=O)c3csc4ccccc34)CC2C)c1
Answer: c. C=CCNc1cc(C)oc(=O)c1C(=O)CC
