B.

13

Let the four consecutive prime numbers be a, b, c and d where a < b < c < d.
∴    abc = 385  and bcd = 1001
∴     HCF = bc
       (H.C.F. of 385 and 1001 is 77)  
     ∴  bc = 77
    ∵   bcd = 1001
      because space space straight d space equals space bcd over bc space equals space 1001 over 77 space equals space 13
