Which of the following could indicate a forgery on a document?

The presence of irregularities in handwriting is a significant indicator of potential forgery. In genuine documents, especially those that are handwritten, there are often natural variations in the way letters are formed, pressure applied to the writing instrument, and overall flow of the handwriting. These nuances are typically absent or less pronounced in forged documents, where the forger may attempt to mimic the original writing style but often fails to replicate these subtle features. As a result, discrepancies in handwriting can raise red flags for forensic analysts and investigators, prompting them to investigate further for authenticity.

In contrast, elements like consistent font size, perfect punctuation, and correct alignment of text are more characteristic of typed documents or those produced with word processing software. These features might indicate a well-prepared document rather than authenticity or forgery. Therefore, while they can help evaluate the presentation quality of a document, they do not serve as effective indicators of forgeries in the same way that irregularities in handwriting do.
