Consider the following statements:
$1$. The element found in bone and teeth is calcium and phosphorus.
$2$. Bones join with muscles with the help of tendons.
$3$. Bone of man became weak in old age due to deficiency of calcium.
Which of the statement(s) given is/are correct?

Match List I with List II and select the correct answers using the codes given the lists.

List I List II
A. Coating on the crown of a tooth $1$. Dentine
B. Mineralized material that forma bulk of a tooth $2$. Enamel
C. Top of a tooth $3$. Tooth root
D. Base of a tooth $4$. Tooth crown
  1. A-$1$, B-$3$, C-$4$, D-$2$
  2. A-$2$, B-$1$, C-$4$, D-$3$
  3. A-$3$, B-$4$, C-$2$, D-$1$
  4. A-$4$, B-$2$, C-$1$, D-$3$
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

The crown coating is enamel (A-2), the bulk of the tooth is dentine (B-1), the top part is the crown (C-4), and the base is the root (D-3). Matching these gives A-2, B-1, C-4, D-3.
