The correct form of the verb is “considering” because it follows the preposition “for.” In English grammar, a verb that comes immediately after a preposition should be in its gerund (-ing) form.
Using the gerund after prepositions helps maintain proper sentence structure and clarity.
For example, phrases like “thank you for helping,” “interested in learning,” and “good at singing” all use the gerund form.
Therefore, in this context, “considering” is the grammatically correct choice to follow “for.”
