Two hormones ….. (a) ….. and ……. (b) …… synthesize in hypothalamus and transport in pituitary gland through …… (c ) …….. and ……. (d) ……. respectively.

Options

A. a = oxytocin `rArr` c = portal circulation
b = ADH `rArr ` d = direct release
B. a = ADH `rArr` c = axonal transport
b= TSHRF `rArr` d = portal circulation
C. a = ACTH `rArr ` c = axonal transport
b = MSH `rArr ` d= portal circulation
D. a = TSHRF `rArr ` c = axonal transport
b = ADH `rArr` d = portasl circulation

Answer

To answer the question, we need to identify the two hormones synthesized in the hypothalamus, the transport mechanisms to the pituitary gland, and fill in the blanks accordingly.

### Step-by-Step Solution:

1. **Identify the Hormones**:
- The two hormones synthesized in the hypothalamus are:
- (a) **ADH** (Antidiuretic Hormone), also known as vasopressin.
- (b) **TSH-RF** (Thyroid Stimulating Hormone Releasing Factor).

2. **Identify the Transport Mechanisms**:
- The transport mechanisms to the pituitary gland are:
- (c) **Axonal Transport**: This is the method through which ADH is transported.
- (d) **Portal Circulation**: This is the method through which TSH-RF is transported.

3. **Fill in the Blanks**:
- Now we can fill in the blanks in the question:
- (a) ADH
- (b) TSH-RF
- (c) Axonal Transport
- (d) Portal Circulation

### Final Answer:
The filled-in statement would be:
"Two hormones (a) **ADH** and (b) **TSH-RF** synthesize in hypothalamus and transport in pituitary gland through (c) **Axonal Transport** and (d) **Portal Circulation** respectively."
