Explanation / Answer

part A

The accleration is instantaneoes rate of change of velocity because there are two accleration.One tangential and one radial

part B

at position 1

v=0

so radial accleration=v^2/r=0 so only tangential accleration so arrow H

part C

at position 1

net accleration is resultant of tangential accleration and radial accleration.so again H

part D

here it will be F
