is this correct?

Compré _____ blusas como mi hermana.
a. tantas
b. tan
c. tantos
d. tanto

D?

Again, Spanish is all about number (singular/plural) and gender (masculine/feminine) so even if you don't understand the sentence, look at "blusas" and pick someth ing that is also plural and feminine. There is only one ch oice here and it is not d.
