Consider the following code segment, which is intended to create and initialize the 2D array words where the length of each word corresponds to the product of the indices of the row and the column it resides in. string[][] words = /*missing code */; Which of the following initializer lists could replace /*missing code*/ so that the code segment works as intended? {{"", "a", "as"}, {"", "b", "be"}, {"", "d", "don"}} O {{"a", "as", "ask"}, {"b", "be", "bet"}, {"d", "do", "don"}} O ""}, {"", "b", "be"}, {"", "do", "dont"}} O {{"a", "a", "a"}, {"", "b", "be"}, {"d", "do", "dont"}} O ""}, {"", "b", "be"}, {"", "d", "do"}}
