Constraint: You must select none, one or more options from a, b, c, or d without using any additional words.
Options:
a CCCCNC(=O)c1nn2c(C(F)(F)F)cc(-c3ccccc3)nc2c1Br
b COc1ccccc1NC(=O)c1ccc(S(=O)(=O)N2CCCC2)cc1
c Cc1ccccc1NC(=O)c1c(C)[nH]c(=S)c(C#N)c1-c1ccc(Cl)cc1
d CCN(C(=O)CSc1cc(-c2ccccc2)c2ccc(OC)cc2n1)C1CCS(=O)(=O)C1
Answer: c. Cc1ccccc1NC(=O)c1c(C)[nH]c(=S)c(C#N)c1-c1ccc(Cl)cc1
