Task: Answer the multiple-choice question.
Query: Which drug exhibits a 18.046\% 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] C=CCN1C(=O)/C(=C2/Sc3ccccc3N2CCCS(=O)(=O)O)SC1=S.c1ccncc1
[b] Cc1cccc(OP(N)(N)=O)c1C
[c] Cn1[nH]c(C(F)(F)F)c(C=NCc2ccc(Cl)cc2)c1=O
[d] Cc1cccc(C)c1N(CC(=O)N1CCN(c2ccccc2F)CC1)S(C)(=O)=O
Answer: b. Cc1cccc(OP(N)(N)=O)c1C
