Task: Answer the multiple choice question.
Question: Which drug has a 12.882\% 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 additional words.
Options:
a: COc1ccc(-c2ocnc2C(=O)Nc2ccccc2N2CCCCC2)cc1
b: CCc1ccc(OCc2n[nH]c(=S)n2Cc2ccccc2)cc1
c: C[N+]12CCC(CC1)C(C(O)(c1ccccc1)c1cccs1)C2.[I-]
d: O=C1CCCCCN1CP(=O)(O)CN1CCCCCC1=O
Answer: d. O=C1CCCCCN1CP(=O)(O)CN1CCCCCC1=O
