Task: Answer the multiple choice question.
Question: Which drug exhibits a 4.051\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
a. CCOC(=O)c1oc2ccccc2c1CSc1nnnn1-c1ccccc1
b. C=CCN1C(=O)/C(=C2\SC(N3CCOCC3)=NC2=O)c2cc(Br)ccc21
c. O=C(CSc1nc2cc(Cl)ccc2s1)c1cc2ccccc2o1
Answer: a. CCOC(=O)c1oc2ccccc2c1CSc1nnnn1-c1ccccc1
