a) 0 blocks
b) 6 blocks
c) 10 blocks
d) 16 blocks

The correct answer is option D.

Explanation:

Number blocks moved north ,= a = 3

Number blocks moved east = b =  5

Number blocks moved south = c =  2

Number blocks moved west = d =  3

Number blocks moved south =  e = 1

Number blocks moved west = f =  2

Total distance covered by Susan = a+b+c+d+e+f

= (3 + 5 + 2 + 3 + 1 + 2)blocks = 16 blocks

16 blocks is her total distance covered.

the nucleus together due to an excess of either protons or neutrons.
