Show answer and explanation

Correct answer: (b) Berzelius

Explanation

The Swedish chemist J. J. Berzelius (1813) proposed writing each element as one or two letters of its name, often its Latin name: H, O, Na (natrium), Fe (ferrum), Cu (cuprum).

This is the system in use today. Dalton had used circles with marks inside them, which were hard to write and print.
