Pick the odd one in each series and select the correct option
(i) Areolar tissue, blood, neuron, tendon
(ii) Salivary gland, gastric gland, tear gland, thyroid gland
(iii) Adrenal gland, sweat gland, milk gland, oil gland

Options

A. (a) `{:(" (i) (ii) (iii)"),("Areolar tissue Gastric gland Milk gland"):}`
B. (b) `{:(" (i) (ii) (iii)"),("Blood Tear gland Oil gland"):}`
C. (c) `{:(" (i) (ii) (iii)"),("Tendon Salivary gland Sweat gland"):}`
D. (d) `{:(" (i) (ii) (iii)"),("Neuron Thyroid gland Adrenal gland"):}`

Explanation

To solve the question of identifying the odd one out in each series, we can follow these steps:

### Step 1: Analyze the first series
**Series:** Areolar tissue, blood, neuron, tendon

- **Areolar tissue, blood, and tendon** are all types of connective tissues.
- **Neuron** is a part of the nervous system and belongs to neural tissue.

**Odd one out:** Neuron

### Step 2: Analyze the second series
**Series:** Salivary gland, gastric gland, tear gland, thyroid gland

- **Salivary gland, gastric gland, and tear gland** are exocrine glands (they secrete their products into ducts).
- **Thyroid gland** is an endocrine gland (it releases hormones directly into the bloodstream).

**Odd one out:** Thyroid gland

### Step 3: Analyze the third series
**Series:** Adrenal gland, sweat gland, milk gland, oil gland

- **Sweat gland, milk gland, and oil gland** are exocrine glands.
- **Adrenal gland** is an endocrine gland.

**Odd one out:** Adrenal gland

### Step 4: Compile the results
- From the first series, the odd one is **Neuron**.
- From the second series, the odd one is **Thyroid gland**.
- From the third series, the odd one is **Adrenal gland**.

### Step 5: Match with the options given
Now we need to find which option matches our findings:
- **Option A:** Incorrect
- **Option B:** Incorrect
- **Option C:** Incorrect
- **Option D:** Correct (Neuron, Thyroid gland, Adrenal gland)

### Final Answer
Hence, the correct answer is **Option D**.
