To determine which of the options is a rational number, we need to understand what a rational number is. A rational number is any number that can be expressed as the quotient or fraction $$ \frac{p}{q} $$, where $$ p $$ and $$ q $$ are integers and $$ q 
eq 0 $$.

Now, let's analyze each option:

A. $$ \pi $$ - This is an irrational number because it cannot be expressed as a fraction of two integers.

B. $$ \sqrt{-1} $$ - This is an imaginary number (denoted as $$ i $$) and is not a rational number.

C. $$ 1.2 $$ - This can be expressed as $$ \frac{12}{10} $$ or $$ \frac{6}{5} $$, which is a fraction of two integers. Therefore, it is a rational number.

D. $$ \sqrt{10} $$ - This is also an irrational number because it cannot be expressed as a fraction of two integers.

Based on this analysis, the correct answer is:

1.1. C
1.1. C
