How many elements has the periodic table been able to identify?

The correct answer is: 118

The periodic table has been able to identify 118 elements. Option A is incorrect because it falls short of the actual number. Option B is also incorrect because it exceeds the number of known elements. Option D is incorrect because it is also higher than the current known elements. The number of elements in the periodic table are always fluctuating, as scientists continue to discover and synthesize new elements. However, as of 2021, the total number of known elements is 118.
