To calculate the number of times a person blinks in a year, we need to know the average number of blinks per minute and then scale that up to a year.

1. An average person blinks about 15 times per minute.
2. Calculate the number of minutes in a year:
- 1 year = 365 days
- 1 day = 24 hours
- 1 hour = 60 minutes

Now, let's do the math:

\[
1 \text{ year} = 365 \text{ days} \times 24 \text{ hours/day} \times 60 \text{ minutes/hour}
= 365 \times 24 \times 60
= 525600 \text{ minutes/year}
\]

3. Now we can calculate the total blinks in a year:

\[
\text{Total blinks} = \text{blinks/minute} \times \text{total minutes in a year}
= 15 \text{ blinks/minute} \times 525600 \text{ minutes/year}
= 7884000 \text{ blinks/year}
\]

4. Finally, to express this in scientific notation:

\[
7884000 = 7.884 \times 10^6
\]

From the provided options, none of them match \(7.884 \times 10^6\), but if we round \(7.884\) to three significant figures, we get:

\[
7.88 \approx 1.314 \times 10^7 \text{ (if we adjust for significant figures)}
\]

However, it appears that I may have made an error in stating my original figure in relation to the options provided.

The correct calculation leads to:

The final answer is \(7.884 \times 10^6\), but based on the available options, if you need a choice among them, it seems that none applies, or further clarification on the scale representation is necessary.

If strictly selecting among provided possibilities and aligning closest via conversion accuracies:

None of the provided answers represent the correct blinking frequency per year properly in context of scientific values.

Therefore, under the conditions provided, please confirm the selections or parameters in retrieved options.
