  In [13], K. Kaur, S. Kamada et al. posed a problem of finding a virtual knot,
if exists, with an unknotting index (n,m), for any pair of non-negative
integers (n,m). In this paper, we address this question by providing infinite
families of virtual knots with unknotting index (n,m), for a given pair of
non-negative integers (n,m). Additionally, we extend our result for virtual
links also.
