Temerity means excessive confidence or boldness; audacity.
“Audacity” means the willingness to take bold risks, hence Option A is the correct answer.
Option B is incorrect because “sincerity” means to be dedicated towards what has to be done, hence it is incorrect.
Option C is incorrect because “intelligence” is the the ability to acquire and apply knowledge and skills, which is not the same as temerity, hence incorrect.
Option D is incorrect because “strength “ is the quality of being physically strong, which is not related to temerity hence it is incorrect.!
