Adding improvement to the signal subset choice by starting with the densest possible lattice for the space is called as

(a) Optimum signal constellation boundaries

(b) Higher density lattice structures

(c) Trellis coded modulation

(d) None of the mentioned

The question was asked in an international level competition.
