The correct answer is (A) Southern and Northern blotting.

Here's why:

1. Southern Blotting: This method is used for detection of a specific DNA sequence in DNA samples. It was named after its inventor, Edwin Southern. The DNA detection is done by hybridization of the sample to a specific DNA probe.

2. Northern Blotting: This method is used for studying gene expression by detection of RNA (or isolated mRNA) in a sample. Like Southern blotting, it involves gel electrophoresis to separate RNA samples by size and detection is done by hybridization to a labeled RNA probe. It was named 'Northern' as a play on the 'Southern' blotting technique.

Therefore, Southern blotting is used for DNA detection and Northern blotting is used for RNA detection.
