This iconic dialogue 'Tumhara naam kya hai Basanti?' is spoken by the character Jai (Amitabh Bachchan) to Basanti (Hema Malini) in the film 'Sholay' (1975). It became one of the most memorable lines in Bollywood history. The other options - 'Ramgarh ke Sholay', 'RamGopal Verma Ke Sholay', and 'Chingari' - are not the correct film titles.
