Match List I (type of coal) with List II (carbon content) and choose the correct answer from the options given below:

List I

i.Peat

ii.Lignite (brown)

iii.Bituminous

iv.Anthracite

List II

a.50-60%

b.70%

c.80%

d.90-95%

Ai-a, ii-b, iii-c, iv-d ✓ Correct

Bi-a, ii-c, iii-b, iv-d

Ci-d, ii-b, iii-c, iv-a

Di-d, ii-c, iii-b, iv-a

Correct answer: (A) i-a, ii-b, iii-c, iv-d

Explanation

Peat pairs with the lowest carbon content of about 50 to 60 percent.

Lignite, the brown coal, pairs with roughly 70 percent carbon.

Bituminous coal pairs with about 80 percent carbon.

Anthracite pairs with the highest carbon of 90 to 95 percent.

Carbon content and heating value rise steadily along this series.

Higher carbon means cleaner burning with less smoke and moisture.
