Answer:
For this case we know that the confidence level is 90% so then the significance level is
and
. And we can find in the normal standard distribution a value who accumulates 0.5 of the area on each tail and we got:

And the best option would be:
1.645
Step-by-step explanation:
We assume that the parameter of interest is
and we can assume that the distribution for this parameter is normally distributed so then the confidence interval assuming a two sided interval is given by:

Where
represent the estimator for the parameter, SE the standard error and
the critical value.
For this case we know that the confidence level is 90% so then the significance level is
and
. And we can find in the normal standard distribution a value who accumulates 0.5 of the area on each tail and we got:

And the best option would be:
