@Ragavi , have you tried specifying the category as Street Address, which will return a candidate at the street level? For example:
https://geocode-api.arcgis.com/arcgis/rest/services/World/GeocodeServer/findAddressCandidates?addres...
The other options is to specify the locationType as 'street', but if only rooftop location coordinates are available for an address, the rooftop geometry will be returned for the geocoded address even when locationType=street is requested. It looks like for the address in your example only rooftop coordinates are available in the data for the World Geocoding Service.

More info about locationType parameter can be found on this page, https://developers.arcgis.com/rest/geocode/api-reference/geocoding-find-address-candidates.htm.
