For a conventional sill-plate anchor bolt set in a concrete foundation, what is the MINIMUM embedment depth of the bolt into the concrete?
a.4 inches
b.7 inches
c.10 inches
d.2 inches

Anchor bolts must extend at least 7 inches into the concrete or grouted masonry to develop adequate holding strength. 4 inches and 2 inches are too shallow to resist uplift and shear reliably, while 10 inches exceeds the minimum and is not the code-required figure.
