Answer 1

Answer:

C. Both statements are correct. Statement II is correct explanation of Statement I.

• Both statements are correct.

• The Law of Octaves, proposed by John Newlands, observed that every eighth element had similar properties to the first.

• This pattern, however, broke down after calcium.

• Therefore, Statement I is correct because the Law of Octaves only applied up to calcium.

• Statement II is also correct because the pattern did not continue after calcium.

• Statement II explains why Statement I is limited to calcium, making option 3 the correct answer
