Why both strands of DNA are not copied during transcription?

Why both strands of DNA are not copied during transcription?
  1. Complementary sequences would code for two different proteins
  2. The two RNA molecules produced would be complementary to each other
  3. The DNA strands are identical
  4. Both A) and B)

Solution

If both strands of DNA act as templates, they would code for RNA molecules with different sequences. Additionally, the two RNA molecules produced would be complementary to each other, which would prevent RNA from being translated into protein.
