I think its A.






A.
century; 1801, 1900


B.
decade; 1701, 1800

C.

D.
century; 1701, 1800

The correct answer is C. decades.

To determine the correct answer, we need to understand the definition of each option and match it with the given information.

A. Centuries: A century refers to a period of 100 years. However, the question specifically mentions the last 40 years, which is not a century. Therefore, option A is incorrect.

B. Millennia: A millennium represents a period of 1000 years. Again, the question only asks about the last 40 years, which is much shorter than a millennium. Therefore, option B is also incorrect.

C. Decades: A decade refers to a period of 10 years. The question states that Jill is interested in the last 40 years, which falls within four decades. This option aligns with the given information, so it is the correct answer.

D. Eras: An era represents a long and distinct period of time characterized by particular events or characteristics. While the last 40 years may be considered as a distinct period, the question specifies that Jill is interested in the last 40 years of the nineteenth century. Therefore, option D, which is not specific to the right time frame, is incorrect.

In conclusion, the correct answer is C. decades.
