C. (a) mRNA , (b) tRNA, (c) rRNA
D. (a) hnRNA, (b) tRNA, (c) mRNA

Answer

To solve the question, we need to identify the roles of three different types of RNA involved in the process of translation. The question states:

(a) provides the template,
(b) brings amino acids and reads the genetic code,
(c) plays structural and catalytic role during translation.

### Step-by-Step Solution:

1. **Identify (a) - Provides the Template:**
- The template for protein synthesis during translation is provided by messenger RNA (mRNA). mRNA is synthesized from DNA and carries the genetic information necessary for the synthesis of proteins.
- Therefore, (a) = **mRNA**.

2. **Identify (b) - Brings Amino Acids and Reads the Genetic Code:**
- Transfer RNA (tRNA) is responsible for bringing the appropriate amino acids to the ribosome during translation. Each tRNA molecule has an anticodon that pairs with the corresponding codon on the mRNA, allowing it to read the genetic code and add the correct amino acid to the growing polypeptide chain.
- Therefore, (b) = **tRNA**.

3. **Identify (c) - Plays Structural and Catalytic Role During Translation:**
- Ribosomal RNA (rRNA) is a key component of the ribosome, which is the site of protein synthesis. rRNA helps to form the structure of the ribosome and also has catalytic properties that facilitate the formation of peptide bonds between amino acids.
- Therefore, (c) = **rRNA**.

### Final Answer:
- (a) = mRNA
- (b) = tRNA
- (c) = rRNA
