I have been asked this question in an interview for job.
The above asked question is from Non-muscle Motility topic in chapter Cytoskeleton and Cell Motility of Cell Biology
Correct choice is C. microvilli
Easy explanation: Villin and fimbrin are globular cross-linking proteins that promote the bundling of actin filaments into parallel and tightly-knit arrays. Such arrays are found in microvilli of epithelial cells.
