What is the $pH$ of $1 \times 10^{-4} \ M \ H_2SO_4$ solution?

Given below are two statements:
Statement-$I$: $pH$ of a $1.0 \times 10^{-8} \ M$ solution of $HCl$ is $8$ at $25^{\circ} C$.
Statement-$II$: $HCl$ is a strong acid and negative log of $H^{+}$ concentration is called $pH$.
In the light of the above statements,choose the most appropriate answer from the options given below:

The $pH$ of the aqueous solution containing $0.49 \ g$ of $H_2SO_4$ in one litre is

The $pH$ of millimolar $HCl$ is

The $pH$ of a $10^{-10} \ M$ $HCl$ solution is approximately

What is the $pH$ of a $2.6 \times 10^{-8} \ M \ H^{+}$ ion solution?
$(\log 2.6 = 0.4150)$
