B. Insulin is a peptide hormone secreted by beta cells of pancreas in pancreatic juice .
C. Parathormone and thyroxine are antagonistic hormone .
How many statements are incorrect ?

Options

A. None
B. One
C. Two
D. All

Answer

To determine how many statements are incorrect, let's analyze each statement one by one:

**Statement A:** "Zone reticulate forms the inner layer of adrenal cortex."
- This statement is **correct**. The adrenal cortex has three layers: zona glomerulosa, zona fasciculata, and zona reticularis. The zona reticularis is indeed the innermost layer of the adrenal cortex.

**Statement B:** "Insulin is a peptide hormone secreted by beta cells of pancreas in pancreatic juice."
- This statement is **incorrect**. Insulin is a peptide hormone secreted by the beta cells of the pancreas, but it is released into the bloodstream, not in pancreatic juice. Pancreatic juice contains digestive enzymes, not hormones.

**Statement C:** "Parathormone and thyroxine are antagonistic hormones."
- This statement is **incorrect**. Parathormone (also known as parathyroid hormone or PTH) and calcitonin are antagonistic hormones that regulate calcium levels in the blood. Thyroxine (T4) is a hormone produced by the thyroid gland that regulates metabolism and is not antagonistic to parathormone.

Now, let's summarize the findings:
- Statement A: Correct
- Statement B: Incorrect
- Statement C: Incorrect

**Conclusion:**
There are **two incorrect statements** (B and C).

### Final Answer:
**Two statements are incorrect.**
