Task: Answer the multiple-choice question.
Query: Which drug exhibits a 2.074\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any additional words.
Options:
(a) CSCCOC(=O)c1[nH]c2c(c1C)C(=O)CC(c1ccco1)C2
(b) O=C(COc1ccccc1)NC1CCCCC1
(c) Cc1ccc(O)c(NC(=O)c2cc(-c3ccc(F)cc3)on2)c1
Answer: a. CSCCOC(=O)c1[nH]c2c(c1C)C(=O)CC(c1ccco1)C2
