The correct Answer is:
To solve the question of identifying the correct pair regarding the essential elements and their functions, we will analyze each option step by step. ### Step 1: Analyze Zinc - Essential for tissue repair Zinc plays a crucial role in various biological functions. It is essential for the activity of over 300 enzymes in the body. Additionally, zinc is important for DNA synthesis, cell division, and protein synthesis, all of which are necessary for tissue regeneration and repair. Therefore, this statement is **correct**. ### Step 2: Analyze Cobalt - Essential for leucocytes Cobalt is primarily known for its role in the formation of vitamin B12 (cobalamin), which is essential for red blood cell formation and neurological function. It is not specifically essential for the formation of leucocytes (white blood cells). Therefore, this statement is **incorrect**. ### Step 3: Analyze Iodine - Synthesis of thyroid hormones Iodine is a critical component in the synthesis of thyroid hormones, particularly thyroxine (T4) and triiodothyronine (T3). These hormones are produced by the thyroid gland and are essential for regulating metabolism and growth. Thus, this statement is **correct**. ### Step 4: Analyze Manganese - Synthesis of insulin Manganese is involved in various enzymatic processes and is a cofactor for several enzymes, but it is not directly involved in the synthesis of insulin. Insulin is primarily synthesized in the pancreas from proinsulin. Therefore, this statement is **incorrect**. ### Conclusion Based on the analysis: - Zinc - Essential for tissue repair: **Correct** - Cobalt - Essential for leucocytes: **Incorrect** - Iodine - Synthesis of thyroid hormones: **Correct** - Manganese - Synthesis of insulin: **Incorrect** The correct pairs are: - Zinc - Essential for tissue repair - Iodine - Synthesis of thyroid hormones Thus, the correct answer is **C** (Iodine - Synthesis of thyroid hormones).
