Task: Answer the MCQ question.
Question: Which drug exhibits a 6.655\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
(a) O=C1CCCC2=C1C(c1ccccc1O)C1=C(CCCC1=O)O2
(b) Cc1c(NC(=O)c2ccccc2NS(=O)(=O)c2ccc(Br)cc2)c(=O)n(-c2ccccc2)n1C
(c) O=C(CCNC(=O)C1CCN(S(=O)(=O)c2ccccc2)CC1)NCc1ccccc1Cl
(d) Nc1nc(NCC(=O)O)nc(N2CCCCCC2)c1[N+](=O)[O-]
Answer: a. O=C1CCCC2=C1C(c1ccccc1O)C1=C(CCCC1=O)O2
