this is an english assignment but i couldnt find english subject in the drop down menu

IC --- ! 3 Many people can recite that E=mc2 and some may even know the value of "c" the constant speed of light in a vacuum (299,792,458 m/s); but was does it really mean? The equation E=mc2 is also known as the mass-equivalence. Simply stated it is the concept that the mass of an object is a measure of its energy content. The mass-energy equivalence arose originally from special relativity as a paradox described by Henri Poincar. Therefore, Albert Einstein was not the first to propose a mass energy relationship. However, Einstein was the first scientist to propose the E = mc2 formula and the first to interpret mass-energy equivalence as a fundamental principle that follows from the relativistic symmetries of space and time. 36 According to the paragraph "c" is: A. dangerous from a nuclear standpoint. C. a discovery of Henri Poincar B. the constant speed of light in a vacuum. D. the mass-energy equivalence. 37 Which word best defines the function of the passage? I A. interrogative B. exclamatory C. derogative D.informative
