D. `{:("(i)","(ii)","(iii)"),("Crypts of lieberkuhn","Pepsin","Bile salts"):}`

Explanation

To solve the question, we need to identify the odd one out in each of the three given series. Let's break it down step by step.

### Step 1: Analyze the first series
**Series:** Villi, Brunner's glands, Crypts of Lieberkuhn, Gastric glands

- **Villi:** Found in the small intestine; they increase the surface area for absorption.
- **Brunner's glands:** Located in the small intestine; they secrete alkaline mucus to protect the intestine.
- **Crypts of Lieberkuhn:** Also found in the small intestine; they secrete intestinal juices.
- **Gastric glands:** Located in the stomach; they secrete gastric juices.

**Odd one out:** Gastric glands (as the first three are found in the small intestine, while gastric glands are in the stomach).

### Step 2: Analyze the second series
**Series:** Pepsin, Lipase, Trypsin, Rennin

- **Pepsin:** A protein-digesting enzyme found in the stomach.
- **Lipase:** An enzyme that digests lipids (fats).
- **Trypsin:** A protein-digesting enzyme produced in the pancreas.
- **Rennin:** An enzyme that curdles milk, also involved in protein digestion.

**Odd one out:** Lipase (as it is a lipid-digesting enzyme, while the others are protein-digesting enzymes).

### Step 3: Analyze the third series
**Series:** Bile salts, Bile pigments, Gall bladder, Gastric juice

- **Bile salts:** Components of bile that help in the digestion of fats.
- **Bile pigments:** Also part of bile, responsible for its color.
- **Gall bladder:** Stores and concentrates bile produced by the liver.
- **Gastric juice:** A digestive fluid produced in the stomach.

**Odd one out:** Gastric juice (as the first three are related to bile, while gastric juice is related to the stomach).

### Final Answer
The odd ones out from each series are:
1. Gastric glands
2. Lipase
3. Gastric juice

### Selected Option
The correct option is: Gastric glands, Lipase, Gastric juice.
