3 notepads of same size and same color =2C1*4C1=8
or 3 notepads of same size and of 3 different colors=2C1*4C3=8

tot=16

This question requires the concept that we have to check for event twice, 1st against size and second against color

Now for selecting a single size out of two we have = 2 ways
For selecting same color we have = 4 ways (any of green blue yellow purple)
so total ways of selecting 3 notepads of same color and and same size = 4x2 = 8 ways

Again for selecting a single size out of two we have = 2 ways
For selecting different color we have = 4ways (gby,bpy,byp,gbp)
so total ways of selecting 3 notepads of different color and and same size = 4x2 = 8 ways

so total no. of ways = 16 [spoiler]Ans C
