Suppose That the RNA Sequence Shown Here Is a Target $\begin{array}{l}5^{\prime}-\text {AAUGCUACG-3' } \\3^{\prime}-\text {UUACGAUGC-5' }\end{array}$

Suppose that the RNA sequence shown here is a target for a microRNA. 5'-UUACGAUGC-3'
Which of these double-stranded precursor RNA molecules could be processed for incorporation into RISC to target the sequence?

A) $\begin{array}{l}5^{\prime}-\text {AAUGCUACG-3' } \\3^{\prime}-\text {UUACGAUGC-5' }\end{array}$
B) $\begin{array}{l}5^{\prime} \text {-UUACGAUGC-3' } \\3^{\prime} \text {-AAUGCUACG-5' }\end{array}$
C) $\begin{array}{l}5^{\prime}-\text {CGUAGCAUU-3' } \\3^{\prime}-\text {GCAUCGUAA-5' }\end{array}$
D) $\begin{array}{l}5^{\prime}-\text {GCAUCGUAA-3' } \\3^{\prime}-\text { CGUAGCAUU-5 }\end{array}$
