Answer:
The correct answer is C. Elizabeth I was skilled at state matters and comfortable wielding power.
Step-by-step explanation:
If you're not sure what the correct answer is, just use the system of elimination.
A is incorrect because she wasn't a ruthless ruler (that type of a ruler would be Bloody Mary); instead, Elizabeth loved her people and cared for them.
B is incorrect because during Elizabeth's reign, England went through many changes in order to become the modern country it is today.
D is incorrect because the Queen had many advisers.
This leaves us with C as the correct answer - Elizabeth was a skilled politician and knew how to rule her country properly - that's why England was very successful at the time.
