Task: Answer the MCQ question.
Question: Which drug exhibits a 9.268\% human ether-à-go-go related gene (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 additional words.
Options:
[a] COc1ccc(OCC(O)CN2C(=O)c3ccccc3S2(=O)=O)cc1
[b] CCOC(=O)C1(Cc2ccc(OC)cc2)CCN(C(=O)c2cc(C)on2)CC1
[c] O=C(NCc1ccncc1)C(=O)NCc1ccncc1
[d] CCCCn1c(N)c(N(CC)C(=O)c2cc(C)cc(C)c2)c(=O)[nH]c1=O
Answer: c. O=C(NCc1ccncc1)C(=O)NCc1ccncc1
