Problem statement: Answer the multiple choice question.
Question: Which drug exhibits a 10.444\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any additional words.
Options:
a) Cc1cccc(OCCC(=O)NCC(=O)Nc2c(C)cccc2C)c1
b) O=C(NC1CCOC1)c1ccc(OC2CCN(CCc3ccccc3)CC2)cc1
c) COC(=O)c1cc(S(=O)(=O)N2CCN(c3ccccc3OC)CC2)cn1C
d) C=C(C)Cn1c(N2CCN(c3ccc(OC)cc3)CC2)nc2c1c(=O)n(C)c(=O)n2C
e) CCCN1CCC(NC(=S)Nc2cccc(Cl)c2Cl)CC1
Answer: d. C=C(C)Cn1c(N2CCN(c3ccc(OC)cc3)CC2)nc2c1c(=O)n(C)c(=O)n2C
