Answer
Statement I: Since 4 × 5 = 20, both 4 and 5 are factors of 20, and 20 is a multiple of both 4 and 5.
∴ Statement I is true.
Statement II: This is the correct definition. If a is a factor of c (i.e., a divides c), then c is called a multiple of a.
∴ Statement II is true.
Both statements are true and Statement II correctly explains Statement I.
Hence, option 3 is the correct option.
