Select the set that correctly matches the type of waste given in Column A with the approximate time taken by it to decompose which is given in Column B.

Column A	Column B
a. Plastic bottle	i. 2 – 5 months
b. Silk scarf	ii. 1 – 2 weeks
c. Cotton shirt	iii. 10 – 30 days
d. Banana peel	iv. 4 years
e. Paper	v. Several years

Choose the correct option :

The correct option is a–v, b–iv, c–i, d–ii, e-iii.

Let us analyze the approximate decomposition time for each type of waste listed in Column A:

a. Plastic bottle: Plastic is non-biodegradable and takes several years (or hundreds of years) to degrade. Thus, a matches with v.

b. Silk scarf: Silk is a natural animal fiber and takes about 4 years to decompose. Thus, b matches with iv.

c. Cotton shirt: Cotton is a natural plant fiber and takes around 2 – 5 months to decompose. Thus, c matches with i.

d. Banana peel: Banana peels and organic food wastes decompose quickly, taking about 1 – 2 weeks. Thus, d matches with ii.

e. Paper: Paper takes approximately 10 – 30 days to completely decompose. Thus, e matches with iii.

Combining these matching pairs:
a – v
b – iv
c – i
d – ii
e – iii

Therefore, the correct matching sequence is a–v, b–iv, c–i, d–ii, e-iii.
