Hello there!,
Well a Igneous rock forms of course by the rate that it cools down in. If there is slow magma cooling then there will be larger crystals. Fast cooling leads to smaller crystals.
Hope I helped!

Statement D is the correct option as the solution will have pH of 3. It has an H3O+ ion concentration of 1 ×
mol/L and is acidic.
Explanation:
It is given in question that solution must have pH of 3. The value if being less than 7 shows that solution is acidic. The pH value of 3 indicates that given solution is highly acidic and has strong acid. Strong acid gets fully dissociated into 
ions.
pH of the solution is calculated as:
pH = -log10[
]
the concentration or molarity of the hydronium ion is given as moles/litre
concentration of hydronium ion in the solution is 1 X
moles/litre
putting the values in the equation:
pH = - log10( 1 X
)
pH = 3 (acidic)
Thus it can be concluded that D option is the right answer.
