Problem statement: Answer the multiple choice question.
Query: Which drug exhibits a -1.733\% 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=c1[nH]c2ccc(S(=O)(=O)N3CCN(c4ccccc4F)CC3)cc2s1
b: CCCC(=O)Oc1ccc(-c2nccc(C(OC)OC)n2)cc1
c: O=C(NC1CCCCC1)C(c1ccc(F)cc1)N(CCCN1CCOCC1)C(=O)c1ccc(CN2CCOCC2)o1
d: COc1ccc(C2C(C#N)=C(N)Oc3cc(O)ccc32)cc1C
Answer: d. COc1ccc(C2C(C#N)=C(N)Oc3cc(O)ccc32)cc1C
