Task: Answer the multiple choice question.
Question: Which drug exhibits a -2.974% human ether-à-go-go related gene (hERG) inhibition at 10uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
a C[C@H](NC(=O)c1ccccc1Cl)C(=O)OCC(=O)N1CCN(c2ccccc2)CC1
b COC(=O)[C@]1(CC(C)C)N[C@H](c2ccc(-c3ccc(F)cc3)c(OC)c2)[C@@H]2C(=O)N(C)C(=O)[C@@H]21.O=C(O)C(F)(F)F
c O=C1OC(c2ccccc2)c2ccc3ccccc3c21
d CCC1(C)Cc2nc3[nH]c(=S)n(-c4ccc(C)cc4)c(=O)c3cc2CO1
Answer: d. CCC1(C)Cc2nc3[nH]c(=S)n(-c4ccc(C)cc4)c(=O)c3cc2CO1
