Milk vein in cow has :

गाय की दूध नाड़ी (Milk vein) में क्या होता है?

Water पानी Blood खून / रक्त Milk दूध Milk and water दूध तथा पानी

The prominent, tortuous vessel visible along the ventral abdomen of high-yielding dairy cows, commonly called the 'milk vein' (scientifically the anterior subcutaneous abdominal vein), carries Blood, NOT milk.
It functions as a major venous pathway returning deoxygenated blood from the mammary gland (udder) back towards the heart via the milk wells.
Approximately 400 to 500 liters of blood must circulate through the udder to synthesize just 1 liter of milk.
Milk itself is synthesized and stored exclusively inside the alveoli, duct systems, and gland cistern of the udder. Thus, the milk vein contains Blood (Option 2).

अधिक दूध देने वाली गायों के पेट के निचले हिस्से पर दिखाई देने वाली उभरी हुई टेढ़ी-मेढ़ी नस को 'दूध नाड़ी' (Milk vein / सबक्यूटेनियस एब्डॉमिनल वेन) कहा जाता है, जिसमें रक्त (खून) बहता है, दूध नहीं।
यह नाड़ी अयन (Udder) से अशुद्ध रक्त को वापस हृदय की ओर ले जाने वाली शिरा (Vein) है।
गाय के अयन में मात्र 1 लीटर दूध के निर्माण के लिए लगभग 400 से 500 लीटर रक्त का परिसंचरण होना आवश्यक होता है।
अतः दूध नाड़ी में केवल रक्त (Blood) होता है (विकल्प 2 सही उत्तर है)।
