According to the arrhenius concept, an acid is a substance that a. is capable of donating one or more h⁺b. tastes bitter c. reacts with the solvent to form the cation formed by autoionization of that solvent d. causes an increase in the concentration of h⁺ in aqueous solutions e. can accept a pair of electrons to form a coordinate covalent bond

a. is capable of donating one or more H⁺

Explanation:

Arrhenius theory:-

The Arrhenius theory was introduced introduced by Swedish scientist named Svante Arrhenius in 1887.

According to the theory, acids are the substances which dissociate in the aqueous medium to produce electrically charged atoms ( may be molecule). Out of these species furnished, one must be a proton or the hydrogen ion, .

Hence, Option A is correct.

i believe it is-

d.) gravity pulled particles of dust and gas together to form planets.

conduction is the transfer of thermal energy (heat in transfer) due to collisions between the molecules in the object. collisions between adjacent atoms and molecules transfer kinetic energy from the warmer to the cooler object. the objects must be in physical contact.
