Problem statement: Answer the multiple choice question.
Question: Which compound exhibits a -2.698\% human ether-à-go-go related gene (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. O=C(CN1CSCC1=O)N1CCN(S(=O)(=O)c2cccc(F)c2)CC1
b. CCCCN(C)Cc1c(O)ccc2c(=O)c(-c3ccccc3OC)coc12
c. C=CCn1c(SCC(N)=O)nnc1-c1cc(Br)ccc1O
d. O=C(CCN1C(=O)C2CCCCC2C1=O)Nc1nc2c(F)cc(F)cc2s1
Answer: c. C=CCn1c(SCC(N)=O)nnc1-c1cc(Br)ccc1O
