Answer : The correct option is, (C) Both the atomic mass and the atomic number increase from left to right.
Explanation :
The general trend of atomic number and atomic mass in the periodic table is,
Both atomic number and atomic mass increase from left to right and decreases from right to left in the periodic table due to the addition of the number of neutrons and the number of protons in the nucleus.
Hence, the correct option is, (C) Both the atomic mass and the atomic number increase from left to right.
