  2. BVitamin A (retinal) deficiency leads to dry and scaly skin
  3. COne of the symptoms of scurvy is pain in the joints
  4. DVitamin B1 (thiamine) deficiency can lead to heart failureCorrect

Explanation

Vitamin B1 (thiamine) deficiency can indeed lead to heart failure. Severe thiamine deficiency causes a condition known as wet beriberi, which affects the cardiovascular system and can result in heart failure due to impaired cardiac function. Option A is incorrect because milk is a rich source of several B-vitamins, especially Vitamin B2 (riboflavin) and Vitamin B12. Options B and C are also scientifically accurate: Vitamin A deficiency causes dry and scaly skin, and scurvy (Vitamin C deficiency) causes pain in the joints.
