  1. Both Assertion and Reason are correct and Reason is the correct explanation for Assertion
  2. Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion
  3. Assertion is correct but Reason is incorrect
  4. Both Assertion and Reason are incorrect

Correct answer: Both Assertion and Reason are correct and Reason is the correct explanation for Assertion

Solution

Archaebacteria (archaea) share several molecular features with eukaryotes, especially in their genome and gene-expression machinery. Since the archaean genome is more similar to the eukaryotic genome than to the bacterial genome, it correctly explains why archaea are considered closer to eukaryotes.
