Statement-1: ${\mathrm{NF}}_3$ has little tendency to act as a donor molecule. 

Statement-2: The highly electronegative F atoms attract electrons and these moments partly cancel the moment from the lone pair.

" ${\mathrm{NF}}_3$ has little tendency to act as a donor molecule" is correct

Because the bond angles in ${\mathrm{NH}}_3$ and ${\mathrm{NH}}_3$ are 103.3° and 103.2°, respectively, indicating that the polarity difference is attributable to differences in bond polarities rather than molecular geometry. Because of these disparities in the availability of unshared electron pairs, ${\mathrm{NH}}_3$ does not operate as an electron pair donor.

"The highly electronegative F atoms attract electrons and these moments partly cancel the moment from the lone pair" is correct because higher nuclear charge value will result in a higher electronegativity value. This occurs because an increase in nuclear charge creates stronger electron attraction.
