The derived units are combinations of the seven base units from the International System of Units (SI). These base units are: meter (m), kilogram (kg), second (s), ampere (A), kelvin (K), mole (mol), and candela (cd).

Let's analyze each option:

A. m (meter), s (second), Pa (Pascal), Nm (Newton meter), and N (Newton).

• Meter and second are base units, not derived.
• Pascal is a derived unit (kg/(m·s²)).
• Newton meter is a derived unit (kg·m²/s²).
• Newton is a derived unit (kg·m/s²).

B. Pa (Pascal), N (Newton), m/s (meter per second), W (Watt).

• All of these are derived units. Pascal is kg/(m·s²), Newton is kg·m/s², meter per second is m/s (a derived unit of speed), and Watt is kg·m²/s³.

C. k (kelvin), m (meter), kg (kilogram), s (second).

• Kelvin, meter, kilogram, and second are all base units, not derived.

D. kg (kilogram), K (kelvin), Pa (Pascal), N (Newton).

• Kilogram and kelvin are base units, not derived.
• Pascal and Newton are derived units.

So, the group of derived units is option B: Pa (Pascal), N (Newton), m/s (meter per second), and W (Watt).
