Explanation for the incorrect options as well thanks

Suppose mortgage interest tax deductions average $7,979 for people with incomes between $70,000 and $300,000 and $365 for those with incomes of $60,000 to $70,000. Suppose also the standard deviations of the housing benefits in these
two categories were equal to $2,650 and $120, respectively.
a. Examine the two standard deviations. What do these indicate about the range of benefits enjoyed by the two groups?
b. Repeat part a using the coefficient of variation as the measure of relative variation.
a. What do the standard deviations indicate about the ranges of benefits?
OA. The lower income group appears to have wider range of benefits because its standard deviation is smaller.
OB. The ranges of benefits appear to be similar because the standard deviations are not significantly different.
OC. The ranges of benefits appear to be similar because both standard deviations are less than the means.
OD. The higher income group appears have a wider range of benefits because its standard deviation is larger.
b. What do the coefficients of variation indicate about the ranges of benefits?
OA. The higher income group appears t have a wider range of benefits because its coefficient of variation is larger.
OB. The lower income group appears to have a wider range of benefits because its coefficient of variation is smaller.
OC. The ranges of benefits appear to be similar because the coefficients of variation are not significantly different.
OD. The ranges of benefits appear to be similar because both coefficients of variation are similar to the standard deviations.
