  In this article, we demonstrate the weak gravitational lensing in the context
of Bocharova-Bronnikov-Melnikov-Bekenstein (BBMB) black hole. To this desire,
we derive the deflection angle of light in a plasma medium by BBMB black hole
using the Gibbons and Werner method. First, we obtain the Gaussian optical
curvature and implement the Gauss-Bonnet theorem to investigate the deflection
angle for spherically symmetric spacetime of BBMB black hole. Moreover, we also
analyze the graphical behavior of deflection angle by BBMB black hole in the
presence of plasma medium.
