Answer: (A)

Verified step by step guidance

1. Understand the concept of transcription: Transcription is the process by which the information in a DNA sequence is copied into a complementary RNA sequence. This is the first step in gene expression.
2. Identify the key components involved in transcription: The main components are the DNA template, RNA polymerase enzyme, and ribonucleotides (the building blocks of RNA).
3. Recognize the role of RNA polymerase: RNA polymerase binds to the DNA template and synthesizes RNA by adding ribonucleotides complementary to the DNA sequence.
4. Differentiate transcription from other processes: Transcription is distinct from DNA replication (which copies DNA) and translation (which synthesizes proteins from RNA).
5. Conclude the process: During transcription, the synthesis of RNA from a DNA template occurs, resulting in a single-stranded RNA molecule that carries the genetic information needed for protein synthesis.
