Given options:
a)33
b)15
c)11
d)14
To determine the correct answer, we need to analyze the given options and find the one that differs from the rest.
Analysis:
Option a) 33: This is an odd number.
Option b) 15: This is an odd number.
Option c) 11: This is a prime number.
Option d) 14: This is an even number.
From the analysis, we can see that option c) 11 is the only prime number among the given options. Therefore, the correct answer is option c) 11.
Hence, the correct answer to the given question is option 'C' which is 11.

Solution:
To find the answer to this question, we need to follow the order of operations. The order of operations is a set of rules that dictate the order in which calculations are performed.
The order of operations is as follows:
1. Parentheses
2. Exponents
3. Multiplication and division (from left to right)
4. Addition and subtraction (from left to right)
Using the order of operations, we can solve the given expression step by step:
Step 1: 3 + 5 × 4 - 7
Step 2: 3 + 20 - 7 (Multiplication is performed before subtraction)
Step 3: 23 - 7 (Addition is performed before subtraction)
Step 4: 16 (Subtraction is performed last)
Therefore, the answer to the given expression is 16.
Hence, option C (11) is incorrect. The correct answer is option C (16).
