Answer:

B) coefficient: subscript

Explanation:

Given

[tex]3H_2O[/tex]

Required

What does 3 and 2 represents

On a general term:

In [tex]nA_m[/tex]

[tex]n = The\ coefficient\ of\ A[/tex]

And

[tex]m = The\ subscript\ of\ A[/tex]

So, by comparing [tex]3H_2O[/tex] with the general term, [tex]nA_m[/tex]

[tex]n = 3[/tex]

[tex]m = 2[/tex]

Hence,

3 = coefficient and 2 = subscript

The correct answer is  A) coefficient: superscript.

Given molecule:-

[tex]3H_2O[/tex]

  In general:

[tex]2B_3[/tex]

2 is the coefficient of B, and 3 is the subscript of B.

 So, by comparing  with the given molecule, [tex]3H_2O[/tex]

3 = coefficient and 2 = subscript

Hence , the correct option is A.
