Task: Answer the multiple choice question.
Query: Which drug has a 17.734\% 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 other words.
Options:
a. O=C(NCC1COc2ccccc2O1)C1C2C=CC3(CN(Cc4cccs4)C(=O)C13)O2
b. CCOC(=O)c1cc(NC(=O)N(C(C)C)C(C)C)c(C)nc1C
c. O=C(NCC1CCCO1)C(c1ccncc1)N(Cc1cccs1)C(=O)CN1C(=O)c2ccccc2S1(=O)=O
d. O=C(CCn1c(=S)oc2ccccc21)Nc1cc([N+](=O)[O-])ccc1F
e. CCC(=O)NCC(c1cccs1)N1CCOCC1.Cl
Answer: d. O=C(CCn1c(=S)oc2ccccc21)Nc1cc([N+](=O)[O-])ccc1F
