Can anyone help me with this chemistry question?

Option A is correct.

Explanation:

In electron dot diagram the valence electrons of an atom are shown by the dots around the symbol of an atom.

Aluminum is present in group 3A.

Its atomic number is 13.

It has three valence electrons.

Electronic configuration of Al;

Al₁₃ = 1s² 2s² 2p⁶ 3s² 3p¹

The electron dot diagram of Al is,

            °Al:

We can see three electrons in the form of dots are present around the Al.

Thus option A is correct because it has three dots around Al. All other options are incorrect because,

Option B contain six electrons around Al.

Option C also contain six electrons.

Option D contain five electrons around Al.
