In C Programming $*,/$ have equal precedence, and associativity is left to right. The minus (-) operator has lower precedence than $*, /$ operator, and associativity is left to right.
Note: we use associativity rule when more than 2 operator having same precedence.
Also, in C language the result of applying a binary operator on integer types (both operands being integers) is ALWAYS INT irrespective of the operation. i.e, $5/2 = 2$ and not $2.5$ as one would normally expect.
$(((2*3)/4)-((3/4)*2))$
$((6/4)-((3/4)*2))$
$(1-((3/4)*2))$
$(1-(0*2))$
$(1-0)$
$1$
Option $B$ is correct.
