**Explanation:**
A factor of a number is a whole number that divides evenly into that number. In other words, if a number can be divided by another number without leaving a remainder, then the second number is a factor of the first number.
Let's consider the options given:
a) 10: 10 is not a factor of every number. For example, 10 is not a factor of 3 because 3 cannot be divided evenly by 10.
b) 1: 1 is a factor of every number. This is because every number can be divided evenly by 1 without leaving a remainder. For example, 1 is a factor of 3 because 3 divided by 1 equals 3 with no remainder.
c) 5: 5 is not a factor of every number. For example, 5 is not a factor of 6 because 6 cannot be divided evenly by 5.
d) 2: 2 is not a factor of every number. For example, 2 is not a factor of 3 because 3 cannot be divided evenly by 2.
Therefore, the correct answer is option 'B' - 1 is a factor of every number.
**Conclusion:**
The number 1 is a factor of every number because every number can be divided evenly by 1 without leaving a remainder.
