Problem statement: Answer the multiple-choice question.
Query: Which compound has a 2.172\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any additional words.
Options:
a: CN(C)c1ccc(NC(=O)CN2C(=O)c3ccccc3C2=O)cc1
b: O=C(CCc1ccc(S(=O)(=O)N2CCOCC2)cc1)N/N=C/c1ccc(O)c(O)c1O
c: CCCCN(C)CCn1c(=S)[nH]c2cc(OCC)c(OCC)cc2c1=O
d: CCNC(=O)c1cc(Br)ccc1Cl
Answer: c. CCCCN(C)CCn1c(=S)[nH]c2cc(OCC)c(OCC)cc2c1=O
