D. `{:("Cristae","Cisternae","Thylakoids"),(" (iii)"," (ii)"," (i)"):}`

Answer

To solve the question, we need to analyze each of the given statements and identify the correct terms associated with them.

### Step-by-Step Solution:

1. **Analyze Statement (i)**:
- The statement refers to "flat membranous sacs in stroma of chloroplasts."
- These structures are known as **thylakoids**. Thylakoids are indeed flat, membranous sacs found within the stroma of chloroplasts and are essential for the light-dependent reactions of photosynthesis.

2. **Analyze Statement (ii)**:
- The statement mentions "infoldings in mitochondria."
- These infoldings are called **cristae**. The inner membrane of mitochondria has these infoldings, which increase the surface area for biochemical reactions, particularly those involved in cellular respiration.

3. **Analyze Statement (iii)**:
- The statement describes "disc-shaped sacs in Golgi apparatus."
- These structures are referred to as **cisternae**. Cisternae are the flattened, disc-shaped membranes that make up the Golgi apparatus and are involved in the processing and packaging of proteins and lipids.

4. **Match Statements with Terms**:
- (i) Thylakoids → Flat membranous sacs in stroma of chloroplasts.
- (ii) Cristae → Infoldings in mitochondria.
- (iii) Cisternae → Disc-shaped sacs in Golgi apparatus.

5. **Select the Correct Option**:
- Based on the analysis, we can conclude that:
- Statement (i) corresponds to thylakoids.
- Statement (ii) corresponds to cristae.
- Statement (iii) corresponds to cisternae.
- Therefore, the correct option that includes all three terms is **option number 3**.

### Final Answer:
The correct option is **option number 3**.
