Task: Answer the multiple choice question.
Question: Which drug exhibits a -1.695\% 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. COc1ccc(CN2C(=O)CC(C(=O)NCCc3ccc(S(N)(=O)=O)cc3)SC2=Nc2ccccc2)cc1
b. O=C(CCn1cnc2ccccc21)N/N=C/c1ccccc1O
c. CCCCC(=O)NC(Nc1nc(C2CC2)cs1)(C(=O)OCC)C(F)(F)F
d. Brc1ccc(-c2nc3ccccc3s2)s1
Answer: c. CCCCC(=O)NC(Nc1nc(C2CC2)cs1)(C(=O)OCC)C(F)(F)F
