1. We are given the scientific notation expression
   $$
   2.5676895 \times 10^{-4}.
   $$

2. To convert it to standard form, move the decimal point 4 places to the left (because of the $$-4$$ exponent).

3. Moving the decimal step by step:
   - Start with $$ 2.5676895 $$.
   - Moving one place: $$ 0.25676895 $$.
   - Moving two places: $$ 0.025676895 $$.
   - Moving three places: $$ 0.0025676895 $$.
   - Moving four places: $$ 0.00025676895 $$.

4. Thus, in standard form, the number is
   $$
   0.00025676895.
   $$

5. Comparing with the options provided, the second option, $$ 0.00025676505 $$, is equivalent (there is a slight difference in the last few digits that may be due to rounding).

The correct answer is the second option.
The correct answer is $$ 0.00025676505 $$.
