Please answer correctly

A C++ program declares the following two variables, select all the answers that apply: char orgName1[100] = "United Nations"; string orgName2( "United States"); Select one or more: O a. To compare orgName2 with orgName3 defined below: string orgName3 ("the u.s.a."); We can do the following: if (orgName2==orgName 3) //other code goes here O b. orgName1 is a fixed-size array of characters. It should be used to hold at most 99 characters. O c. Unlike orgName1, orgName2 can be modified to store as many characters as long as it does not exceed its maximal size allowed by the compiler. O d. orgName2 is an object-oriented string object. It's equipped with a large collection of member functions, e.g., at() and size()
