Hi Farhan Khan,
Usually, helper-address command is executed under the layer 3 interface, so in your case it will be under the VLAN interfaces like that:
interface vlan 101
ip helper-address 192.168.100.1
Also, have you got DHCP scopes configured on the router and has it got the return routes to all the networks on the switch? Can you show the output of following commands from the router:
show run | sec dhcp
show ip route
