Step 1: Understand DNA forms.
B-DNA is the most common form of DNA and can be synthesized from RNA in processes such as reverse transcription.
Step 2: Analyze the options.
A-DNA, C-DNA, and Z-DNA are different structural forms of DNA but are not directly made from RNA.
B-DNA is the form that is most commonly synthesized from RNA during reverse transcription in certain organisms.
Conclusion: The correct answer is (B) B-DNA.
Let the function $ f(x) $ be defined as follows: $$ f(x) = \begin{cases} (1 + | \sin x |)^{\frac{a}{|\sin x|}}, & -\frac{\pi}{6}<x<0 \\b, & x = 0 \\ \frac{\tan 2x}{\tan 3x}, & 0<x<\frac{\pi}{6} \end{cases} $$ Then the values of $ a $ and $ b $ are:
