The problem may ___ in the lack of financing.

• A. Lie
• B. Live
• C. Lead
• D. Load

Answer: (A)

The idea here is expressing where the problem comes from using the verb lie in a fixed phrase. When we say a problem may lie in something, we mean that thing is the source or cause of the problem.

With a modal like may, the main verb stays in its base form, so the correct wording is may lie. That’s why the sentence uses lie rather than lies. Using lie also matches the idiom lie in the lack of financing, meaning the lack of financing is where the problem originates.

Other options don’t fit the sense or grammar. Live would suggest a persons or things exist in a place, which isn’t the intended idea here. Lead would require a structure like may lead to, to show a consequence, not may lie in. Load has no meaning in this context.

So the sentence correctly points to the lack of financing as the underlying cause.
