Task: Answer the multiple-choice question.
Query: Which drug has a -2.131\% 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 additional words.
Options:
a. COc1ccc(/C(=C/Nc2cccc(Br)c2)C(C)=O)cc1OC
b. O=C(CCN1C(=O)C2C3C=CC(C4CC34)C2C1=O)Oc1ccc(Br)cc1
c. O=C(c1cccc(Br)c1)N1CCN(c2ccc(N3CCOCC3)nn2)CC1
d. O=c1cc(CO)oc(CN2CCN(Cc3ccccc3)CC2)c1O
Answer: c. O=C(c1cccc(Br)c1)N1CCN(c2ccc(N3CCOCC3)nn2)CC1
