Solution

The correct option is D Both Assertion and Reason are incorrect.
RNA produced by transcription in eukaryotic cells are processed and transported to cytoplasm where they are used as template for protein synthesis, a process also known as translation. RNAs are not involved in the process of photosynthesis which is carried out in chloroplast. Assertion is wrong. RNA splicing is the process of removal of introns from primary transcript and ligation of exons to form a continuous reading frame. It does not removes toxins. Reason is wrong.
