   • B. Vitamin B12
   • C. Vitamin C

   Answer: D

   Vitamin D is naturally synthesized in the human body when the skin is exposed to ultraviolet B rays from sunlight, which is why it is often called the 'sunshine vitamin'.

5. Q5 · Trigonometry

   If sin θ + cos θ = √2, then what is the value of tan θ + cot θ?

   • A. 1
   • B. 2
   • C. √2
   • D. 4
   Answer and solution

   Answer: B

   Squaring both sides: sin²θ + cos²θ + 2sinθcosθ = 2. Since sin²θ + cos²θ = 1, we get 2sinθcosθ = 1. Now tan θ + cot θ = (sin θ/cos θ) + (cos θ/sin θ) = (sin²θ + cos²θ)/(sinθcosθ) = 1/(sinθcosθ) = 2.

6. Q6 · Statistics

   The marks obtained by 5 students are 20, 25, 30, 35, and 40. What is the mean of their marks?

   • A. 28
