Among the gases (a)−(e),\left(a\right) - \left(e\right), the gases that cause greenhouse effect are:
\left(a\right){CO}_{2}
(b)H2O\left(b\right){H}_{2}O
\left(c\right)CFCs<br/>(d)O2<br />\left(d\right){O}_{2}
\left(e\right){O}_{3}

Options

  1. A(a),(b),(c)\left(a\right), \left(b\right), \left(c\right) and \left(d\right)
  2. B(a),(b),(c)\left(a\right), \left(b\right), \left(c\right) and \left(e\right)
  3. C(a)\left(a\right) and (d)\left(d\right)
  4. D (a),(c),(d)\left(a\right), \left(c\right), \left(d\right) and \left(e\right)

Correct answer

B. (a),(b),(c)\left(a\right), \left(b\right), \left(c\right) and \left(e\right)
