The correct option is A D
We have to determine the letter that can be divided into two symmetrical halves.
∙ If two halves of the letter are mirror halves of each other, then the shape of the letter is divided into symmetrical halves. If not, then it is not symmetrical.
∙ Letter D is symmetrical about the given line. If we write the letter D on a piece of paper and fold it along the line, then both halves will be mirror halves. It can be divided into symmetrical halves.
∙ Letter C is not symmetrical about the given line. If we write the letter C on a piece of paper and fold it along the line, then both halves will not be mirror halves. It cannot be divided into symmetrical halves.
∙ Letter B is not symmetrical about the given line. If we write the letter B on a piece of paper and fold it along the line, then both halves will not be mirror halves. It cannot be divided into symmetrical halves.
∙ Letter A is not symmetrical about the given line. If we write the letter A on a piece of paper and fold it along the line, then both halves will not be mirror halves. It cannot be divided into symmetrical halves.
Hence, A is the correct option.
