Given below are your statements (A-D) each with one or two balnks. Select the option which ocrrectly fills the blanks in any two statements.
(A) Thymus secretes (i) which help in differentiating of ii
(B) The adrenal medulla secretes i which stimulates the breakdown of ii to increased the blood glucose concentration during emergensy situations.
(C) The Leydig's cells or i present in the intertubular spaces in testis, produce a group of hormones called ii
(D) Thyroid gland secretes i and trliodothyronine which contain ii

Options

A. i melatonin, ii T-lymphocytes
i adrenaline, ii fat
B. i catecholamine, ii glycogen
i interstitial cells, ii LH
C. i catecholamine, ii glycogen
i thyroxine, ii iodine
D. i parathyroid hormone, ii calcium
i thymosin, ii B-lymphocytes

Answer

To solve the question, we need to fill in the blanks for the statements (A-D) with the correct terms based on our knowledge of biology, specifically hormonal functions and the glands involved.

### Step-by-Step Solution:

**Statement A:**
- Thymus secretes **(i)** **thymosin**, which helps in differentiating of **(ii)** **T lymphocytes**.
- **Filled Statement:** Thymus secretes thymosin which helps in differentiating of T lymphocytes.

**Statement B:**
- The adrenal medulla secretes **(i)** **catecholamines**, which stimulate the breakdown of **(ii)** **glycogen** to increase the blood glucose concentration during emergency situations.
- **Filled Statement:** The adrenal medulla secretes catecholamines which stimulate the breakdown of glycogen to increase the blood glucose concentration during emergency situations.

**Statement C:**
- The Leydig's cells or **(i)** **interstitial cells** present in the intertubular spaces in the testis produce a group of hormones called **(ii)** **androgens**.
- **Filled Statement:** The Leydig's cells or interstitial cells present in the intertubular spaces in the testis produce a group of hormones called androgens.

**Statement D:**
- Thyroid gland secretes **(i)** **thyroxine** and triiodothyronine which contain **(ii)** **iodine**.
- **Filled Statement:** Thyroid gland secretes thyroxine and triiodothyronine which contain iodine.

### Correctly Filled Statements:
1. **A:** thymosin, T lymphocytes
2. **B:** catecholamines, glycogen
3. **C:** interstitial cells, androgens
4. **D:** thyroxine, iodine

### Answer Selection:
From the analysis, the correct option that fills the blanks accurately in two statements is:
- **Option C:** catecholamines, glycogen (for Statement B) and thyroxine, iodine (for Statement D).
