Finally I have figured out whether a field has options or not.
Unfortunately every field in message is associated with FieldOptions. By
default, each field has DefaultOptions .So I could make pointer comparision
and say whether a field has Custom field options or not.
Final question remains:
FieldOptions is just a proto message defined in descriptor.proto:
https://github.com/protocolbuffers/protobuf/blob/2220670ed97fb5d52868a0316054748e6354b6aa/src/google/protobuf/descriptor.proto#L509

KakshmiKanth, in addition, please take a look at HasExtension and
GetExtension:
https://developers.google.com/protocol-buffers/docs/reference/cpp-generated#extension
to
get your extension field from FieldOptions.
