Task: Answer the multiple choice question.
Query: Which drug exhibits a -3.475\% 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 other words.
Options:
[a] CC1Cc2ccccc2N1C(=O)c1cccnc1
[b] C=CCNC(=O)N[C@@H](CCSC)C(=O)OC
[c] O=C(c1cc(COc2ccc3ncccc3c2)on1)N1CCC[C@H]1CO
[d] NS(=O)(=O)c1ccc(NC(=O)C(=O)NCCC(=O)O)cc1
Answer: b. C=CCNC(=O)N[C@@H](CCSC)C(=O)OC
