**Hint:**The ability to do work is energy . This energy can be measured using multiple different types of units. Calorie and Joule are the units of energy, calorie is in the CGS system and Joule is in the SI system. The relation between calorie and joule is fully proportional. This means that any change in Calorie will change its equivalent value in Joules.

**Complete step by step answer:**

The relationship between calorie and joule is fully proportional. Which means that the calorie

is directly proportional to the joule. That means-

When the value in terms of calorie increases, its corresponding value in joules also increases at a rate of 4.2.

When the value in terms of calorie decreases, its corresponding value in joules also decreases at a rate of 4.2.

The relation between Calorie and Joule is-

1 calorie = 4.2 joules

1 Calorie/kcal = 4.2 kilojoules.

Therefore 1 joule=1/4.2 calorie.

That is 0.238 calorie which is equivalent to 0.24 calorie.

Hence option A is the correct option.

Additional Information:

Calorie | Joule |

1 | 4.184 |

20 | 83.68 |

30 | 125.52 |

40 | 167.36 |

50 | 209.2 |

100 | 418.4 |

1000 or 1Kcal | 4184 |

5000 or 5Kcal | 20920 |

10000 or 10 Kcal | 41840 |

500 | 2092 |

Joule | Calorie or Kilocalorie |

1 | 0.000239006 |

10 | 0.00239006 |

20 | 0.00478011 |

30 | 0.00717017 |

40 | 0.00956023 |

50 | 0.0119503 |

100 | 0.0239006 |

500 | 0.119503 |

1000 | 0239006 |

5000 | 1.195029 |

Note: One calorie is the unit of energy.

One Calorie or kilocalorie is the unit of energy that has 1000 calories.

Joule is the unit of energy.

Kilojoule is the unit of energy that has 1000 joules.

The conversion between two units of energy that is calorie to joule and vice versa is crucial in solving problems.
