Which condition will cause the statement block of the if statement to execute only when count is 0?

To determine which condition will cause the statement block of the if statement to execute only when count is 0, we first review the given question and answer options.
Option 1: 'if count = 0 :' uses a single equals sign. In Python (and many similar languages), '=' is the assignment operator, not a comparison. This would attempt to assign 0 to count rather than check count, and would typically result in a syntax error or unintended behavior, so it does not represent a valid condition that runs when count is 0.
Option 2: 'if count < 0 :' checks whether count is less than zero. This will execute only when count is negative, not when count equals zero, so it does not satisfy the requirement of triggering specifically at 0.
Option 3: 'if count =< 0 :' contains a malformed operator. The correct operator for 'less than or equal to' is '<='; as written, this is a syntax error and cannot function as a conditional check. Therefore it cannot cause execution precisely at count being 0.
Option 4: 'if count == 0 :' uses the double equals sign, which is the canonical equality comparison in Python. This condition evaluates to true exactly when count is 0, so the indented block will run only in that case. The colon at the end is required to introduce the block, and the overall form matches proper Python syntax for a conditional.
In summary, the only option that correctly expresses a condition that executes exclusively when count is 0 is the one using 'count == 0' with proper syntax and comparison semantics, while the others either misuse assignment, use the wrong comparison, or contain a syntax error in the operator.
