How many elements are there in the periodic table?

The correct answer is: 118

The periodic table is a tabular arrangement of all known chemical elements, organized by their atomic number and chemical properties. As of now, there are 118 currently known elements in the periodic table. Option A, 109, is incorrect because it does not reflect the most recent discoveries and additions to the periodic table. Option C, 90, is incorrect because it is significantly lower than the actual number of elements in the periodic table. Option D, 68, is also incorrect for the same reason as option C. Therefore, the most accurate and up-to-date answer would be option B, 118.
