Ok so this is how I know. Whenever I want to find what key a song is in this is what I do. You look at the last sharp, in this case it would be C#. What note comes after the last sharp? D comes after C. So the name of this key is D Major!!! I use this trick all the time since I play piano and violin and let me tell you it is such a life saver haha. Anyways hope this helps! Have a great day!!

The correct answer is a.the castrati were classical singers with very high voice equivalent to that of a soprano, mezzo-soprano or contralto. this effect of high voice was produced by castration before puberty or an endocrinological condition. the castrati first started signing at the church but then they also sang at the opera. they did not only sang in italy but in many churches in europe. finally, they were singing male and female roles as well.
