The following activity can be termed as an example of possibilism:

Ports on the coasts

The correct answer is Option (2) → Ports on the coasts

• Possibilism means that while nature provides opportunities and limitations, human beings use technology and knowledge to modify and utilise nature.

• Building ports on the coasts is a clear example of possibilism, as humans use coastal geography but develop technology and infrastructure to expand trade and transport.

Other options:

• Forest worship and being afraid of nature → examples of environmental determinism (nature dominating humans).

• Collecting fruits and herbs → an example of natural dependence, not possibilism.
