5<10 and 12>7 or not 7>4 groups as ((5<10) and (12>7)) or (not (7>4)) = True or False = True. Correct option: (a) True.

Concept — logical-operator precedence in Python

Among Python's logical operators the precedence order is: not (highest) → and → or (lowest), and all comparison operators (<, >) bind tighter than any of them. So the expression is implicitly bracketed as:

((5 < 10) and (12 > 7)) or (not (7 > 4))

Step-by-step trace

StepEvaluatesResultExpression so far
15 < 10TrueTrue and 12>7 or not 7>4
212 > 7TrueTrue and True or not 7>4
37 > 4TrueTrue and True or not True
4not True (not first)FalseTrue and True or False
5True and True (and next)TrueTrue or False
6True or False (or last)TrueTrue

Run it:

print(5<10 and 12>7 or not 7>4)

Output:

True

(Short-circuit view: the left side of the or is already True, so the whole expression is True no matter what not 7>4 gives.)
