Answers
GPT 3.5
The reason hydrogen is placed with the elements in Group 1A is because it has the same number of valence electrons as the elements in that group (1 valence electron). This similarity in valence electrons leads to similar chemical properties among the elements in Group 1A and hydrogen.
e
so is it a b c or d
