Task: Answer the MCQ question.
Question: Which drug exhibits a -0.378\% 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 additional words.
Options:
(a) O=C(O)C(Cc1cc2ccccc2[nH]1)N1C(=O)C2CC=C(Cl)CC2C1=O
(b) Cn1c(N)c(C(=O)c2ccccc2)c(=O)n(C)c1=O
(c) CCn1nc(NC(=O)c2ccncc2)c2cc3ccccc3nc21
(d) O=C(CSc1ccc(Br)cc1)Nc1ccccc1Oc1ccccc1
(e) CS(=O)(=O)N(CC(=O)N1CCCCC1)c1ccc2c(c1)OCO2
Answer: a. O=C(O)C(Cc1cc2ccccc2[nH]1)N1C(=O)C2CC=C(Cl)CC2C1=O
