What could be the source of this issue?

An app builder notices several Accounts converted from Leads are missing information they expected

to be caught via Account validation rules.

What could be the source of this issue?
A . The lead settings are unchecked to require validation for converted leads.
B . Account validation rules fail to validate on records converted from a lead.
C . The lead settings are allowing users to intentionally bypass validation rules.
D . Lead validation rules fail to validate on records when they are being converted.

Answer: A

Explanation:

The lead settings have an option to require validation for converted leads. If this option is unchecked, then the Account validation rules will not be enforced when a lead is converted to an Account. This could result in missing or incorrect information on the Account records
