  2. (b) H2 is readily available as a transportation fuel.
  3. (c) Petroleum is a mixture of hydrocarbons.
  4. (d) Methane hydrate can never be developed as a commercial energy resource.

Interpretation Introduction

Interpretation: The true statements should be identified from the given statement.

Concept introduction:
