Friends the correct answer is 'd '
so far seven(7) persons acted as Deputy prime ministers
in the union cabinet of India
they are
1) Sardar Vallabhbhai Patel *Gujarat *( 1947 -1950 ) 3yrs 122 days .the first Dy.p.m of india n minister of home affairs
(longest served dy. p.m)
( under the p.m. Nehru)

2)Morarji Desai -surat,*Gujarat*(1967-69) 2yrs 128 days. the second dy. p.m of india.
( under the p.m
Indira Gandhi)

3) Charan Singh -baghpat, *U.P*(1977-79) 173 days
( under the p.m. .morarji)

4)Jagjivan Ram

-sasaram,*Bihar*(1977-79)
185 days( under the p.m. morarji)

5)Y.B.Chavan - Satara*Maharashtra*((1979-80) 170 days
( shortest served dy. p.m)
( under the p.m. Charan Singh)

6) Devilal - Rohtak n Sikar, Haryana *(1990-91) 223 days
( served as dy. p.m under 2 P.Ms n two parties - V.P. Singh n Chandra Sekar)

7) L.k. Advani -Gandhinagar*Gujarat *(2002-04)1yr 328 days
( under the p.m. a.b. vajpayee)

please see that there is only one dy. p.m( jagjivan Ram)from Bihar.

but there are 3 Dy P.Ms (1. Patel 2.Morarji and 3.Advani) from Gujarat .

please also note even if Patel is taken/ considered as a member of Constitutent assembly,came from the
the United provinces, still the answer' d' ' holds tight

right as there is no other STATE that has sent two Dy.P.Ms
interestingly all the above 3 Dy P..Ms from Gujarat 1,2.n 7 ( Patel, Morarji n Advani ) mentioned above have served for longer periods
please let me enlightened if l am wrong.
